GENERAL DESCRIPTION
The AD7665 is a 16-bit, 570 kSPS, charge redistribution SAR,
analog-to-digital converter that operates from a single 5 V power
supply. It contains a high speed 16-bit sampling ADC, a resistor
input scaler that allows various input ranges, an internal conver-
sion clock, error correction circuits, and both serial and parallel
system interface ports.
The AD7665 is hardware factory-calibrated and is comprehen-
sively 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 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 AD7665 is a very high speed (570 kSPS in Warp Mode
and 500 kSPS in Normal Mode), charge redistribution, 16-bit
SAR ADC.
2. Single-Supply Operation
The AD7665 operates from a single 5 V supply, dissipates
only 64 mW typical, even lower when a reduced throughput
is used with the reduced power mode (Impulse) and a power-
down mode.
3. Superior INL
The AD7665 has a maximum integral nonlinearity of 2.5 LSB
with no missing 16-bit code.
4. Serial or Parallel Interface
Versatile parallel (8 bits or 16 bits) or 2-wire serial interface
arrangement compatible with both 3 V or 5 V logic.
