PRODUCT HIGHLIGHTS

1. Fast T hroughput

GENERAL DESCRIPT ION

T he AD7667 is a 1 MSPS, charge redistribution, 16-bit

SAR ADC with internal error correction circuitry.

T he AD7667 is a 16-bit, 1 MSPS, charge redistribution SAR,

analog-to-digital converter that operates from a single 5 V

power supply. T he 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.

2. Internal Reference

The AD7667 has an internal reference and allows for an

external reference to be used.

3. Superior INL

It features a very high sampling rate mode (Warp) and, for

asynchronous conversion rate applications, a fast mode

(Normal) and, for low power applications, a reduced power

mode (Impulse) where the power is scaled with the through-

put.

T he AD7667 has a maximum integral nonlinearity of 2.5

LSB with no missing 16-bit code.

4. Single-Supply Operation

The AD7667 operates from a single 5 V supply and dissipates

a typical of 112 mW. In impulse mode, its power dissi-

pation decreases with the throughput. It consumes 7 µW

maximum when in power-down.

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 speci-

fied from –40°C to +85°C.

5. Serial or Parallel Interface

Versatile parallel or 2-wire serial interface arrangement

compatible with both 3 V or 5 V logic.
