ADS7800AH

Analog To Digital Converters (ADC) Overview

The ADS7800AH is a 12-bit successive approximation register (SAR) analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a single-ended input and parallel interface, operating with a sampling rate of 333 kS/s. The device requires both analog and digital power supplies within the range of 4.75 V to 5.25 V. Key performance metrics include a signal-to-noise ratio (SNR) of 73 dB and a signal-to-noise and distortion ratio (SINAD) of 72 dB. Differential nonlinearity (DNL) is specified at +/- 0.75 LSB, while integral nonlinearity (INL) is +/- 0.5 LSB. It operates within a temperature range of -40°C to +85°C and is housed in an SOIC-24 package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'AH' against the official datasheet to confirm temperature grade and package variant. Ensure compatibility with existing board layouts regarding the SOIC-24 footprint and pin configuration. Cross-reference the manufacturer's latest documentation for any updates to electrical specifications or recommended operating conditions prior to finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit resolution and parallel interface are required for moderate-speed applications. Consider the single-ended input architecture and 5V supply requirement. Evaluate the thermal performance within the industrial temperature range if deployed in harsh environments. Compare against other SAR ADCs if differential inputs or lower power consumption are critical system constraints.
