GENERAL DESCRIPTION

PRODUCT HIGHLIGHTS

The AD7650 is a 16-bit, 570 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, error correction circuits, and both

serial and parallel system interface ports.

1. Fast Throughput

The AD7650 is a 570 kSPS, charge redistribution, 16-bit

SAR ADC.

2. Single-Supply Operation

The AD7650 operates from a single 5 V supply. In impulse

mode, its power dissipation decreases with the throughput from

77 mW at 444 kSPS throughput to, for instance, only 21 µW

at a 100 SPS throughput. It consumes 7 µW maximum when

in power-down.

It features a very high sampling rate mode (Warp) and, for

asynchronous conversion rate applications, a fast mode (Normal)

and, for low power applications, a reduced power mode (Impulse)

where the power is scaled with the throughput.

It is fabricated using Analog Devices’ high-performance,

0.6 micron CMOS process and is available in a 48-lead LQFP

or in a tiny 48-lead Chip Scale package with operation specified

from –40°C to +85°C.

3. Serial or Parallel Interface

Versatile parallel or 2-wire serial interface arrangement com-

patible with both 3 V or 5 V logic.
