AD7893 IC Chip

AD7893（LC²MOS 12-Bit, Serial 6 μS ADC in 8-Pin Package）

Introduction

The AD7893 is a fast, 12-bit ADC that operates from a single +5 V supply and is housed in a small 8-pin mini-DIP and 8-pin SOIC. The part contains a 6 μs successive approximation A/D converter, an on-chip track/hold amplifier, an on-chip clock and a high speed serial interface.

Output data from the AD7893 is provided via a high-speed serial interface port. This two-wire serial interface, featuring a serial clock input and a serial data output, allows for seamless data transmission, with the external serial clock accessing the serial data from the part.

In addition to traditional dc accuracy specifications such as lin-earity, full-scale and offset errors, the AD7893 is also specified for dynamic performance parameters, including harmonic distortion and signal-to-noise ratio.

Fabricated using Analog Devices’ Linear Compatible CMOS (LC²MOS) process, the AD7893 combines precision bipolar circuits with low-power CMOS logic. It is available in both a small, 8-pin mini-DIP and an 8-pin SOIC package.
