TLC0831IP

Analog To Digital Converters (ADC) Overview

The TLC0831IP is an 8-bit successive-approximation analog-to-digital converter manufactured by Texas Instruments in a plastic DIP package. It features a single-channel serial output interface compatible with standard shift registers and microprocessors. The device operates with a supply voltage of 4.5 V to 5.5 V and supports clock frequencies up to 600 kHz, achieving a conversion time of 32 μs at 250 kHz. It accommodates input ranges from 0 V to 5 V and offers ratiometric operation or independent reference capabilities. Designed for interchangeability with National Semiconductor ADC0831 devices, it provides a total unadjusted error of ±1 LSB.

Analog To Digital Converters (ADC) Procurement Notes

Verify the component suffix 'I' confirms the industrial temperature range specification of -40°C to 85°C. Confirm the package designation 'P' corresponds to the 8-pin Plastic Dual In-Line (PDIP) form factor. Ensure procurement sources provide documentation verifying compliance with RoHS standards and lead finish specifications as indicated in current packaging addendums.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 8-bit resolution is sufficient for the application's accuracy requirements. Choose this part over multiplexed variants if only a single analog channel requires conversion. Consider the serial interface constraints regarding clock duty cycle and setup times when designing the processor timing logic.

Analog To Digital Converters (ADC) Part Context

This device belongs to the TLC083x family of 8-bit analog-to-digital converters produced by Texas Instruments. It serves as a direct functional replacement for the National Semiconductor ADC0831.
