GENERAL DESCRIPTION

AD7660/AD7661 AD7664/AD7666 AD7667

The AD7655 is a low cost, 4-channel, 16-bit, charge redistribution

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

power supply. It contains two low noise, wide bandwidth track-and-

hold amplifiers that allow simultaneous sampling, a high speed

1 MSPS 16-bit sampling ADC, an internal conversion clock,

error correction circuits, and both serial and parallel system

interface ports. Each track-and-hold has a multiplexer in front

to provide a 4-channel input ADC.

PRODUCT HIGHLIGHTS

1. Multichannel ADC

The AD7655 features a very high sampling rate mode (Normal)

and, for low power applications, a reduced power mode (Impulse)

where the power is scaled with the throughput. It is available

in 48-lead LQFP or 48-lead LFCSP packages with operation

specified from –40∞C to +85∞C.

The AD7655 features 4-channel inputs with two sample-

and-hold circuits that allow simultaneous sampling.

2. Fast Throughput

The AD7655 is a very high speed (1 MSPS in normal mode

and 888 kSPS in impulse mode), charge redistribution, 16-bit

SAR ADC that avoids pipeline delay.

3. Single-Supply Operation

The AD7655 operates from a single 5 V supply and dissipates

only 120 mW typical, even lower when a reduced throughput

is used with the reduced power mode (Impulse) and a power-

down mode.

4. Serial or Parallel Interface

Versatile parallel or 2-wire serial interface arrangement

compatible with both 3 V or 5 V logic.
