GENERAL DESCRIPTION
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.
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.
PRODUCT HIGHLIGHTS
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
W
at a 100 SPS throughput. It consumes 7
W maximum when
in power-down.
3. Serial or Parallel Interface
Versatile parallel or 2-wire serial interface arrangement com-
patible with both 3 V or 5 V logic.
