GENERAL DESCRIPTION
The AD7653 is a 16-bit, 1 MSPS, 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, internal conversion clock, internal reference, error
correction circuits, and both serial and parallel system interface
ports. It features a very high sampling rate mode (Warp), a fast
mode (Normal) for asynchronous conversion rate applications,
and a reduced power mode (Impulse) for low power applica-
tions where power is scaled with the throughput. The AD7653 is
fabricated using Analog Devices’ high performance, 0.6 micron
CMOS process, with correspondingly low cost. It is available in
a 48-lead LQFP and a tiny 48-lead LFCSP with operation
specified from –40°C to +85°C.

PRODUCT HIGHLIGHTS
1.
Fast Throughput.
The AD7653 is a 1 MSPS, charge redistribution, 16-bit SAR
ADC with internal error correction circuitry.
2.
Internal Reference.
The AD7653 has an internal reference with a typical
temperature drift of 7 ppm/°C.
3.
Single-Supply Operation.
The AD7653 operates from a single 5 V supply. In Impulse
mode, its power dissipation decreases with the throughput.
4.
Serial or Parallel Interface.
Versatile parallel or 2-wire serial interface arrangement is
compatible with both 3 V and 5 V logic.
