TLV0832CDR

Analog To Digital Converters (ADC) Overview

The TLV0832CDR is an 8-bit successive-approximation analog-to-digital converter manufactured by Texas Instruments. It features a multiplexed twin-channel architecture supporting single-ended or differential input configurations. The device operates on a single supply voltage ranging from 2.7 V to 3.6 V, with the internal reference typically tied to VCC. It utilizes a serial interface compatible with standard microprocessors and shift registers. Key electrical specifications include a maximum clock frequency of 600 kHz at 3.3 V, a conversion time of 32 µs at 250 kHz, and a total unadjusted error of ±1 LSB. The component is housed in an 8-pin SOIC package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'CDR' corresponds to the commercial temperature range (0°C to 70°C) and tape-and-reel packaging format. Confirm that the intended application environment remains within these thermal limits. Ensure the design accommodates the 2.7 V to 3.6 V supply voltage constraints. Validate pin compatibility with the target PCB footprint before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 8-bit resolution ADC with dual channels is required in a compact surface-mount package. It is suitable for designs needing a simple serial interface without complex parallel data lines. Consider the TLV0831 if only a single channel is necessary, or the TLV0834/TLV0838 for higher channel counts. Ensure the system clock frequency does not exceed the specified maximum for the chosen supply voltage.

Analog To Digital Converters (ADC) Part Context

The TLV0832 belongs to the TLV083x family of low-power, 8-bit A/D converters from Texas Instruments. This series is functionally equivalent to older National Semiconductor parts like the ADC0832 but optimized for lower voltage operation. The 'C' suffix denotes the commercial temperature grade, while 'I' indicates industrial grade. The 'D' signifies the SOIC package, and 'R' indicates reel packaging.

Analog To Digital Converters (ADC) Replacement Considerations

The datasheet explicitly states the device is designed to be functionally equivalent to the National Semiconductor ADC0831 and ADC0832 at a 3 V supply. Designers migrating from these legacy parts should verify pinout compatibility and ensure the new supply voltage range meets their system requirements.
