GENERAL DESCRIPTION
The AD7664 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.
The AD7664 is hardware factory calibrated and is comprehensively
tested to ensure such ac parameters as signal-to-noise ratio (SNR)
and total harmonic distortion (THD), in addition to the more
traditional dc parameters of gain, offset, and linearity.
It features a very high sampling rate mode (Warp) 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 fabricated using Analog Devices’ high-performance, 0.6
micron CMOS process, with correspondingly low cost and is
available in a 48-lead LQFP with operation specified from –40
°
C
to +85
°
C.
PRODUCT HIGHLIGHTS
1. Fast Throughput
The AD7664 is a 570 kSPS, charge redistribution, 16-bit
SAR ADC with internal error correction circuitry.
2. Superior INL
The AD7664 has a maximum integral nonlinearity of 2.5 LSBs
with no missing 16-bit code.
3. Single-Supply Operation
The AD7664 operates from a single 5 V supply and typically
dissipates only 97 mW. In impulse mode, its power dissipa-
tion decreases with the throughput to, for instance, only 21
μ
W
at a 100 SPS throughput. It consumes 7
μ
W maximum when in
power-down.
4. Serial or Parallel Interface
Versatile parallel or 2-wire serial interface arrangement com-
patible with both 3 V or 5 V logic.
