The ADS7862 is a 12-bit, 500kHz analog-to-digital converter from TI that features 4 fully differential input channels that can be grouped into two pairs for high-speed simultaneous signal acquisition. It also supports a parallel interface and control inputs to minimize software overhead. The device is available in a TQFP-32 package and operates over a temperature range of -40°C to +85°C.
The ADS7862 is a high‑speed, low‑power, dual 12‑bit analog‑to‑digital converter with four fully differential inputs grouped into two simultaneous‑sampling channels. It operates from a single +5 V supply, offers an internal 2.5 V reference, and provides a typical common‑mode rejection of 80 dB.
Key specifications include a 500 kHz maximum throughput per channel, 40 mW power consumption, and operation over a temperature range of 40 °C to +85 °C in a TQFP‑32 package. The datasheet also contains ordering information, mechanical drawings, and the standard TI product warranty notice.
