GENERAL DESCRIPTION

PRODUCT HIGHLIGHTS

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.

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.

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.

3. Fast Throughput

The AD7677 is a 1 MSPS, charge redistribution, 16-bit SAR

ADC with internal error correction circuitry.

4. Single-Supply Operation

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 operates from a single 5 V supply and typically

dissipates only 115 mW. Its power dissipation decreases

with the throughput. It consumes 7 µW maximum when in

power-down.

The AD7677 is available in a 48-lead LQFP or a tiny 48-lead

LFCSP with operation specified from –40°C to +85°C.

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.
