TLV0834CPWRG4 Equivalent & Substitute Parts

Part Overview

The TLV0834CPWRG4 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 support for 2, 3, or 4 input channels, SPI data interface, and external voltage reference configuration. The TLV0834CPWRG4 is classified as obsolete, necessitating identification of active equivalent alternatives to maintain design continuity and ensure long-term component availability for production and maintenance applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLV0834CPWRG4 is determined by strict equivalence across the following critical parameters: 8-bit resolution, 41k samples per second sampling rate, support for 2/3/4 input channels with differential, pseudo-differential, and single-ended input types, SPI data interface, SAR architecture with single A/D converter in MUX-ADC configuration, external reference type, 2.7V to 3.6V supply voltage range for both analog and digital domains, 16-TSSOP package, surface mount mounting type, and compliance certifications (ROHS3, MSL 1).

Two active substitute parts meet these electrical and mechanical criteria:

1. TLV0834CPWR — Parametric equivalent with identical electrical specifications, differing only in packaging format (Tape & Reel vs. Tube).
2. TLV0834IPW — Upgrade substitute with identical electrical specifications and extended operating temperature range (-40°C ~ 85°C vs. 0°C ~ 70°C), differing in packaging format (Tube).

Parameter Comparison

Engineering Selection Recommendations

TLV0834CPWR is the direct parametric equivalent for applications requiring identical electrical and thermal specifications within the 0°C to 70°C operating range. This part maintains active product status and full compliance with ROHS3 and REACH requirements. Selection of TLV0834CPWR is appropriate for designs with standard industrial temperature requirements and where Tape & Reel packaging is compatible with assembly processes.

TLV0834IPW is the upgrade substitute for applications requiring extended operating temperature capability from -40°C to 85°C. This part is suitable for industrial, automotive, or military-grade applications where wider temperature operation is specified. TLV0834IPW maintains active product status and identical compliance certifications. The extended temperature range provides design margin for harsh environment deployments without modification to electrical interface or firmware.

Both substitute parts are manufactured by Texas Instruments under the same base product number (TLV0834) and share identical pin configuration, package footprint, and electrical interface characteristics with the obsolete TLV0834CPWRG4, enabling direct board-level substitution.

Frequently Asked Questions (FAQ)

Q: Can TLV0834CPWR be used as a direct replacement for TLV0834CPWRG4?

A: Yes. TLV0834CPWR is a parametric equivalent with identical electrical specifications, resolution, sampling rate, input channel configuration, data interface, supply voltage requirements, and operating temperature range. The only difference is packaging format (Tape & Reel vs. Tube). Pin configuration and package footprint are identical, enabling direct substitution on PCB assemblies.

Q: What is the difference between TLV0834CPWR and TLV0834IPW?

A: Both parts share identical electrical specifications and package footprint. The primary difference is operating temperature range: TLV0834CPWR operates from 0°C to 70°C, while TLV0834IPW operates from -40°C to 85°C. TLV0834IPW is suitable for applications requiring extended temperature operation. Both are active products with current manufacturing support.

Q: Is TLV0834IPW compatible with designs originally specified for TLV0834CPWRG4?

A: Yes. TLV0834IPW is electrically and mechanically compatible with TLV0834CPWRG4. The extended operating temperature range (-40°C to 85°C) is a superset of the original specification (0°C to 70°C), making it suitable for the same applications and for designs requiring wider temperature operation.

Q: What packaging formats are available for these substitute parts?

A: TLV0834CPWR is supplied in Tape & Reel (TR) format for high-volume automated assembly. TLV0834IPW is supplied in Tube format for lower-volume or manual assembly processes. Both use identical 16-TSSOP surface mount packages with 0.173" width and 4.40mm body dimensions.

Q: Are these substitute parts RoHS and REACH compliant?

A: Yes. Both TLV0834CPWR and TLV0834IPW are ROHS3 compliant and REACH unaffected, matching the compliance status of the original TLV0834CPWRG4. Moisture sensitivity level is MSL 1 (Unlimited) for all three parts.

Q: Which substitute should be selected for new designs?

A: For new designs, TLV0834IPW is recommended due to its active product status, extended operating temperature range, and long-term availability assurance. TLV0834CPWR is appropriate for designs with standard industrial temperature requirements or where Tape & Reel packaging is preferred for assembly automation.
