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), a fast mode
(Normal) for asynchronous conversion rate applications, 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 and a tiny 48-lead LFCSP 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 dissipates
only a maximum of 115 mW. In Impulse Mode, its power
dissipation decreases with the throughput to, for instance, only
21
W at a 100 SPS throughput. It consumes 7 W maximum
when in power-down.
4. Serial or Parallel Interface
Versatile parallel or 2-wire serial interface arrangement
compatible with both 3 V or 5 V logic.
