EVAL-AD7765EDZ(Rev0) Datasheet PDF - Analog Devices

GENERAL DESCRIPTION
The AD7765 is a high performance, 24-bit Σ-Δ analog-to-digital converter (ADC). It combines wide input bandwidth, high speed, and performance of 112 dB dynamic range at a 156 kHz output data rate. With excellent dc specifications, the converter is ideal for high speed data acquisition of ac signals where dc data is also required.
