GENERAL DESCRIPTION
The AD7621 is a 16-bit, 3 MSPS, charge redistribution
SAR, fully differential analog-to-digital converter that
operates from a single 2.5 V power supply. The part
contains a high-speed 16-bit sampling ADC, an internal
conversion clock, an internal reference buffer, error
correction circuits, and both serial and parallel system
interface ports.
It features a very high sampling rate mode (Wideband
Warp) for undersampling applications and, for asyn-
chronous 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 available in a 48-lead LQFP or a 48-lead LFCSP
with operation specified from –40°C to +85°C.
PRODUCT HIGHLIGHTS
1. High resolution and Fast Throughput
The AD7621 is a 3 MSPS, charge redistribution,
16-bit SAR ADC ( no latency ).
2. Excellent accuracy
The AD7621 has a maximum integral nonlinearity of 1
LSB with no missing 16-bit code.
3. Single-Supply Operation
The AD7621 operates from a single 2.5 V supply and
typically dissipates only 100 mW. In impulse mode,
its power dissipation decreases with the throughput and
it features a power-down mode.
5. Serial or Parallel Interface
Versatile parallel (16 or 8 bits bus) or 2-wire serial
interface arrangement compatible with either 2.5V,
3.3V or 5 V logic.
