ADS7810UB

Analog To Digital Converters (ADC) Overview

The ADS7810UB is a 12-bit successive approximation analog-to-digital converter (ADC) in a 28-pin SOIC package. It features an industry-standard ±10V input range and operates on dual ±5V supplies. The device achieves an 800kHz sampling rate with a 1.25µs throughput time. Key electrical specifications include a maximum integral nonlinearity (INL) of ±3 LSB, a maximum differential nonlinearity (DNL) of ±3 LSB, and a minimum signal-to-noise and distortion ratio (SINAD) of 69dB at a 250kHz input frequency. It includes an internal 2.5V reference and parallel data outputs.
