The AD7652 is a 16-bit, 500 kSPS, charge redistribution SAR

analog-to-digital converter that operates from a single 5 V

power supply. The part contains a high speed 16-bit sampling

ADC, an internal conversion clock, internal reference, error

correction circuits, and both serial and parallel system interface

ports.

Simultaneous

PRODUCT HIGHLIGHTS

1. Fast Throughput.

The AD7652 is a 500 kSPS, charge redistribution, 16-bit

SAR ADC with internal error correction circuitry.

The AD7652 is fabricated using Analog Devices’ high perform-

ance, 0.6 micron CMOS process, with correspondingly low cost,

and is available in a 48-lead LQFP and a tiny 48-lead LFCSP

with operation specified from –40°C to +85°C.

2. Internal Reference.

The AD7652 has an internal reference with a typical

temperature drift of 7 ppm/°C.

3. Single-Supply Operation.

The AD7652 operates from a single 5 V supply. Its power

dissipation decreases with throughput.

4. Serial or Parallel Interface.

Versatile parallel or 2-wire serial interface arrangement is

compatible with both 3 V and 5 V logic.
