TLV0834IPWRG4 Equivalent & Substitute Parts

Part Overview

The TLV0834IPWRG4 is an 8-bit Analog to Digital Converter (ADC) manufactured by Texas Instruments, designed for data acquisition applications requiring multi-channel input capability. This device features a Successive Approximation Register (SAR) architecture with configurable input modes and SPI digital interface, operating across a 2.7V to 3.6V supply voltage range.

The TLV0834IPWRG4 is currently discontinued at DiGi Electronics. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for production and maintenance applications.

Substitute Part Grouping Explanation

Substitute parts for the TLV0834IPWRG4 must maintain electrical and mechanical compatibility based on the following critical parameters:

8-bit resolution and 41k sampling rate
Multi-channel input configuration (2, 3, 4 inputs)
Support for Differential, Pseudo-Differential, and Single Ended input modes
SPI digital communication interface
SAR architecture with single A/D converter
External reference voltage requirement
2.7V to 3.6V supply voltage range for both analog and digital domains
16-TSSOP surface mount package
Operating temperature range of -40°C to 85°C

The TLV0834IPWR qualifies as a direct substitute based on identical electrical specifications and package configuration. The primary distinction is packaging format: the substitute part is supplied in Tape & Reel (TR) format rather than the original packaging specification.

Engineering Selection Recommendations

The TLV0834IPWR is the recommended substitute for the discontinued TLV0834IPWRG4. Both parts are manufactured by Texas Instruments and share identical electrical specifications, pin configuration, and functional capabilities. The substitute part maintains active product status, ensuring ongoing availability and manufacturer support.

Both parts comply with ROHS3 standards and are REACH unaffected, meeting current environmental and regulatory requirements. The Moisture Sensitivity Level of 1 (Unlimited) indicates no special moisture handling requirements for either part.

The primary consideration for component selection is packaging format. The substitute part is supplied in Tape & Reel (TR) format, which is standard for high-volume production environments. If the original packaging format is a specific requirement, this distinction should be evaluated against procurement and assembly process capabilities.

Frequently Asked Questions (FAQ)

Q: Are the TLV0834IPWRG4 and TLV0834IPWR electrically identical?

A: Yes. Both parts are identical in electrical specifications, including resolution, sampling rate, input configuration, supply voltage requirements, and operating temperature range. They share the same base product number (TLV0834) and are pin-compatible in 16-TSSOP packages.

Q: What is the difference between these two part numbers?

A: The primary difference is packaging format. The TLV0834IPWRG4 uses standard packaging, while the TLV0834IPWR is supplied in Tape & Reel (TR) format. This distinction affects procurement and assembly processes but does not impact electrical performance or functionality.

Q: Can the TLV0834IPWR be used as a direct replacement in existing designs?

A: Yes. The TLV0834IPWR is a direct functional and mechanical replacement. No design modifications are required. The 16-TSSOP package dimensions and pin assignments are identical, and all electrical parameters match the original specification.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical RoHS3 compliance status and REACH unaffected designation. Moisture Sensitivity Level (MSL) is 1 (Unlimited) for both parts, indicating no special handling requirements.

Q: Why is the original part discontinued?

A: The TLV0834IPWRG4 is discontinued at DiGi Electronics. The TLV0834IPWR remains in active production status, making it the appropriate choice for new designs and component replenishment.

Q: What inventory considerations should be evaluated?

A: The TLV0834IPWR has significantly higher inventory availability (5083 Pcs) compared to the original part (944 Pcs). This availability advantage supports both immediate procurement needs and long-term supply chain planning.
