BUF04701AIPWR Equivalent & Substitute Parts

Part Overview

The BUF04701AIPWR is a video amplifier integrated circuit manufactured by Texas Instruments, designed specifically for TFT-LCD panel gamma buffer applications. This 4-channel rail-to-rail amplifier operates in the 14-TSSOP package and is classified as an obsolete product. Due to its obsolete status and limited availability for new production runs, identifying equivalent and substitute components is essential for design continuity and system reliability in TFT-LCD display applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BUF04701AIPWR is determined by the following critical parameters:

Package Compatibility: All substitute parts must use the 14-TSSOP surface mount package to ensure direct PCB footprint compatibility without layout modifications.

Electrical Performance: Substitute parts must maintain rail-to-rail output capability and support the same supply voltage range (3.5V ~ 12V single supply or ±1.75V ~ 6V dual supply) to function within existing power distribution architectures.

Circuit Configuration: All candidates must provide 4 independent amplifier circuits to match the original channel count and functional density.

Bandwidth and Slew Rate: The -3dB bandwidth of 8 MHz and slew rate of 10V/µs define the signal fidelity requirements for TFT-LCD gamma buffer applications. Substitute parts meeting or exceeding these specifications maintain signal integrity.

Output Current: The 32 mA per-channel output current specification must be met to ensure adequate drive capability for LCD panel control circuits.

Compliance: All substitute parts must maintain ROHS3 compliance and unlimited moisture sensitivity level (MSL 1) for manufacturing and storage compatibility.

Parameter Comparison

Engineering Selection Recommendations

Direct Package Substitutes (14-TSSOP):

The ADA4807-4ARUZ and ADA4807-4ARUZ-R7 from Analog Devices provide direct 14-TSSOP package compatibility with active product status. Both variants maintain the required 4-channel configuration and rail-to-rail output capability. The ADA4807 series exceeds the bandwidth and slew rate specifications of the BUF04701AIPWR, providing enhanced performance margin. Both variants carry MSL 1 rating and ROHS3 compliance, matching the original part's environmental specifications.

The MCP6H94-E/ST and MCP6H94T-E/ST from Microchip Technology offer 14-TSSOP package compatibility with active product status. These parts match the -3dB bandwidth (10 MHz) and slew rate (10V/µs) specifications of the original component. Both maintain the required supply voltage range and output current capability. The primary distinction between these variants is packaging format: MCP6H94-E/ST is supplied in tube packaging, while MCP6H94T-E/ST is supplied in tape and reel format.

Alternative Package Consideration:

The BUF04701AIDGSR represents a Texas Instruments alternative within the same base product family, utilizing a 10-VSSOP package instead of 14-TSSOP. This part maintains electrical equivalence but requires PCB layout modification due to different package geometry. Product status is listed as "Not For New Designs," and MSL rating is 2 (1 Year), indicating more restrictive moisture handling requirements compared to the original part.

Obsolete Product Alternatives:

The MCP6H84-E/ST is classified as obsolete and should not be selected for new designs despite meeting most electrical parameters. This part is included for reference only in legacy system maintenance scenarios.

Compliance and Certification:

All recommended active-status substitutes maintain ROHS3 compliance and carry unlimited moisture sensitivity ratings (MSL 1), ensuring compatibility with standard manufacturing and storage protocols. Supply voltage ranges across all candidates support the original 3.5V to 12V single-supply specification.

Frequently Asked Questions (FAQ)

Q: Can the BUF04701AIDGSR be used as a direct replacement for the BUF04701AIPWR?

A: The BUF04701AIDGSR maintains electrical equivalence but uses a 10-VSSOP package instead of the original 14-TSSOP package. Direct PCB substitution is not possible without layout redesign. Additionally, this part carries "Not For New Designs" status and has MSL 2 moisture sensitivity, requiring more stringent handling procedures than the original MSL 1 rating.

Q: What is the primary difference between MCP6H94-E/ST and MCP6H94T-E/ST?

A: Both parts are electrically identical with matching specifications. The difference is packaging format: MCP6H94-E/ST is supplied in tube packaging, while MCP6H94T-E/ST is supplied in tape and reel format. Selection depends on assembly line requirements and volume handling procedures.

Q: Do the Analog Devices ADA4807 variants provide better performance than the original BUF04701AIPWR?

A: The ADA4807-4ARUZ and ADA4807-4ARUZ-R7 exceed the original specifications in bandwidth (180 MHz versus 8 MHz) and slew rate (250V/µs versus 10V/µs). These enhanced specifications provide additional performance margin but are not required for standard TFT-LCD gamma buffer applications. Both variants maintain the required 4-channel configuration, rail-to-rail output, and compatible supply voltage range.

Q: Are all substitute parts ROHS3 compliant?

A: All substitute parts listed carry ROHS3 compliance certification. However, the BUF04701AIDGSR has MSL 2 rating (1 Year moisture sensitivity) compared to MSL 1 (Unlimited) for other candidates. This affects storage and handling requirements during manufacturing.

Q: Which substitute offers the closest electrical match to the BUF04701AIPWR?

A: The MCP6H94-E/ST and MCP6H94T-E/ST provide the closest electrical match, with identical -3dB bandwidth (10 MHz) and slew rate (10V/µs) specifications. Both maintain the same supply voltage range, output current capability, and 4-channel configuration. These parts carry active product status and MSL 1 rating, matching the original part's environmental specifications.

Q: Can MCP6H74-E/ST or MCP6H74T-E/ST be used as substitutes?

A: The MCP6H74 series meets package and basic functional requirements but operates at reduced bandwidth (2.7 MHz) and slew rate (2V/µs) compared to the original 8 MHz and 10V/µs specifications. These parts are suitable only for applications with lower bandwidth requirements than the original design.

Q: What is the significance of product status classifications?

A: Active status indicates the manufacturer continues production and supports the component for new designs. "Not For New Designs" status indicates limited production support. Obsolete status indicates the manufacturer has discontinued production. For new system designs, active-status components are recommended to ensure long-term availability and manufacturing support.
