AD7876BR

The AD7876BR from Analog Devices is a fast, complete, 12-bit analog-to-digital converter (ADC) designed for high-performance data acquisition. It integrates a track-and-hold amplifier, an 8 μs successive approximation ADC, and a 3V buried Zener reference on a single chip.

Key electrical specifications include a 12-bit resolution and a sampling rate of 100 kSPS. The device boasts a low power consumption of 60 mW typical and a fast data access time of 57 ns. It operates from a single supply voltage of -4.75V minimum and draws a supply current of 8 mA. The input impedance is high at 9 GΩ.

This ADC features a self-contained internal clock that is laser-trimmed for accurate conversion time control, though an external clock can override it if needed. It supports parallel, byte, and serial data output formats, ensuring easy interfacing with modern microprocessors and digital signal processors. The operating temperature range is -40°C to 85°C.

The AD7876BR is available in a 24-pin SOIC package suitable for surface mounting. Its versatile interface and robust performance make it suitable for various data acquisition applications.
