GENERAL DESCRIPTION
The AD7667 is a 16-bit, 1 MSPS, 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, internal reference, error
correction circuits, and both serial and parallel system inter-
face ports. It features a very high sampling rate mode (Warp), a
fast mode (Normal) for asynchronous applications, and a
reduced power mode (Impulse) for low power applications
where power is scaled with the throughput. The AD7667 is
hardware factory-calibrated and comprehensively tested to
ensure ac parameters such as signal-to-noise ratio (SNR) and
total harmonic distortion (THD) in addition to the more
traditional dc parameters of gain, offset, and linearity. Operation
is specified from –40°C to +85°C.

PRODUCT HIGHLIGHTS
1.
Fast Throughput.
The AD7667 is a 1 MSPS, charge redistribution, 16-bit SAR
ADC with internal error correction circuitry.
2.
Superior INL.
The AD7667 has a maximum integral nonlinearity of
2.0 LSBs with no missing 16-bit codes.
3.
Internal Reference.
The AD7667 has an internal reference with a typical
temperature drift of 3 ppm/°C.
4.
Single-Supply Operation.
The AD7667 operates from a single 5 V supply. In Impulse
mode, its power dissipation decreases with throughput.
5.
Serial or Parallel Interface.
Versatile parallel or 2-wire serial interface arrangement is
compatible with both 3 V and 5 V logic.
