GENERAL DESCRIPTION
The AD7677 is a 16-bit, 1 MSPS, charge redistribution SAR,
fully differential, 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 AD7677 is hardware factory calibrated and 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 applica-
tions; and, for low power applications, a reduced power mode
(Impulse) where the power is scaled with the throughput.
The AD7677 is available in a 48-lead LQFP or a tiny 48-lead
LFCSP with operation specified from –40
°C to +85°C.
PRODUCT HIGHLIGHTS
1. Excellent INL
The AD7677 has a maximum integral nonlinearity of 1 LSB
with a no missing 16-bit code.
2. Superior AC Performances
The AD7677 has a minimum dynamic of 92 dB, 94 dB typical.
3. Fast Throughput
The AD7677 is a 1 MSPS, charge redistribution, 16-bit SAR
ADC with internal error correction circuitry.
4. Single-Supply Operation
The AD7677 operates from a single 5 V supply and typically
dissipates only 115 mW. Its power dissipation decreases
with the throughput. It consumes 7
W maximum when in
power-down.
5. Serial or Parallel Interface
Versatile parallel (8 bits or 16 bits) or 2-wire serial inter-
face arrangement compatible with both 3 V or 5 V logic.
