GENERAL DESCRIPTION
The AD7651* is a 16-bit, 100 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 inter-
face ports.
The AD7651 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.
*
Patent Pending.

1.
Fast Throughput.
The AD7651 is a 100 kSPS, charge redistribution, 16-bit
SAR ADC with internal error correction circuitry.
2.
Internal Reference.
The AD7651 has an internal reference with a typical
temperature drift of 7 ppm/°C.
3.
Single-Supply Operation.
The AD7651 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.
