TSV634AIPT Equivalent & Substitute Parts

Part Overview

The TSV634AIPT is a general-purpose operational amplifier manufactured by STMicroelectronics, configured as a 4-circuit rail-to-rail amplifier in a 14-TSSOP surface mount package. This device is classified as Active product status and carries AEC-Q100 automotive qualification. The TSV634AIPT is specified for applications requiring low-power operation across extended temperature ranges from -40°C to 125°C with supply voltages between 1.5V and 5.5V.

Equivalent and substitute parts are identified based on matching functional architecture (4-circuit amplifier configuration), identical package format (14-TSSOP), rail-to-rail output capability, and compatible electrical operating parameters. Substitutes are selected where supply voltage ranges, temperature ratings, and output drive capabilities align with or exceed the original specification.

Engineering Selection Recommendations

For Direct Replacement (Automotive-Grade Applications):

The TSV634AIPT carries AEC-Q100 automotive qualification. Direct substitutes maintaining automotive-grade status and full -40°C to 125°C temperature range are limited within the provided substitute list. ISL28413FVZ and ISL28414FVZ from Renesas Electronics maintain the full temperature range and are suitable for non-automotive applications requiring equivalent performance. Both parts are ROHS3 compliant and REACH unaffected.

For General-Purpose Applications (Extended Temperature Range):

MCP6004T-E/ST (Microchip Technology) provides direct functional equivalence with -40°C to 125°C operating range, ROHS3 compliance, and Cut Tape & Digi-Reel packaging matching the original part format. This part supports supply voltages up to 6V, exceeding the TSV634AIPT maximum of 5.5V.

For Performance-Enhanced Applications:

AD8604DRUZ-REEL (Analog Devices) offers improved dynamic performance with 6V/µs slew rate and 8.4 MHz gain bandwidth product while maintaining -40°C to 125°C temperature range and ROHS3 compliance. This part requires minimum supply voltage of 2.7V (versus 1.5V for TSV634AIPT) and is available in Cut Tape & Digi-Reel packaging.

For Limited Temperature Range Applications (Industrial Grade):

BD12734FVJ-E2 and LMR934FVJ-E2 (Rohm Semiconductor) operate to 85°C maximum and are suitable for industrial applications not requiring full automotive temperature range. LMR934FVJ-E2 provides superior output drive capability (90 mA per channel) compared to TSV634AIPT (74 mA per channel).

All recommended substitutes maintain 14-TSSOP package format, 4-circuit configuration, rail-to-rail output, and surface mount mounting type. Selection should be based on specific application requirements for supply voltage range, operating temperature, and dynamic performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can AD8604ARUZ or AD8604DRUZ be used as direct replacements for TSV634AIPT?

A: AD8604 variants are functionally compatible in 14-TSSOP package format with 4-circuit rail-to-rail configuration. However, AD8604 requires minimum supply voltage of 2.7V, while TSV634AIPT operates from 1.5V. Applications using supply voltages below 2.7V cannot use AD8604 variants. AD8604 offers superior slew rate (6V/µs versus 0.34V/µs) and gain bandwidth product (8.4 MHz versus 880 kHz).

Q: What is the difference between MCP6004-E/ST, MCP6004-I/ST, and MCP6004T-E/ST?

A: All three variants share identical electrical specifications and 14-TSSOP package format. The primary differences are operating temperature range and packaging format. MCP6004-E/ST and MCP6004T-E/ST support -40°C to 125°C; MCP6004-I/ST supports -40°C to 85°C. MCP6004T-E/ST is supplied in Cut Tape & Digi-Reel format, matching the TSV634AIPT packaging. MCP6004-E/ST and MCP6004-I/ST are supplied in Tube format.

Q: Are ISL28413FVZ and ISL28414FVZ interchangeable?

A: Both parts share identical package format (14-TSSOP), circuit count (4), and temperature range (-40°C to 125°C). ISL28414FVZ provides higher slew rate (2.5V/µs versus 1V/µs) and gain bandwidth product (5 MHz versus 2 MHz), with correspondingly higher supply current (300µA versus 90µA) and output drive capability (31 mA versus 22 mA per channel). Selection depends on application bandwidth and power consumption requirements.

Q: Why do some substitutes have different maximum operating temperatures?

A: Operating temperature range is a specified parameter determined by device design and qualification testing. BD12734FVJ-E2 and LMR934FVJ-E2 are specified to 85°C maximum, suitable for industrial applications. TSV634AIPT, ISL28413FVZ, ISL28414FVZ, AD8604 variants, and MCP6004-E/ST and MCP6004T-E/ST support -40°C to 125°C, suitable for automotive and extended-range applications. Application requirements determine appropriate selection.

Q: What is the significance of packaging format (Tube versus Cut Tape & Digi-Reel)?

A: Packaging format affects supply and handling logistics but does not alter electrical performance. Cut Tape & Digi-Reel format (TSV634AIPT, AD8604DRUZ-REEL, BD12734FVJ-E2, LMR934FVJ-E2, MCP6004T-E/ST) is suitable for automated assembly processes. Tube format (AD8604ARUZ, AD8604DRUZ, ISL28413FVZ, ISL28414FVZ, MCP6004-E/ST, MCP6004-I/ST) is suitable for manual assembly or lower-volume applications. Electrical specifications remain identical regardless of packaging format.

Q: Can TSV634AIPT be used in applications requiring supply voltages below 2.7V?

A: TSV634AIPT supports supply voltages from 1.5V to 5.5V. AD8604 variants require minimum 2.7V supply. For applications requiring operation below 2.7V, TSV634AIPT, MCP6004 variants, ISL28413FVZ, ISL28414FVZ, BD12734FVJ-E2, and LMR934FVJ-E2 are suitable. BD12734FVJ-E2 and LMR934FVJ-E2 require minimum 1.8V supply.

Q: What is the impact of input offset voltage differences on circuit design?

A: Input offset voltage is a specified parameter affecting DC accuracy in precision applications. TSV634AIPT specifies 800µV offset. Substitutes range from 80µV (AD8604ARUZ) to 4500µV (MCP6004 variants). Lower offset voltage reduces DC error in high-gain or precision measurement circuits. Application requirements for DC accuracy determine acceptable offset voltage range.

Q: Are all substitute parts ROHS3 compliant?

A: All substitute parts listed are ROHS3 compliant and REACH unaffected, matching TSV634AIPT compliance status. This ensures compatibility with environmental and regulatory requirements across all listed alternatives.
