GENERAL DESCRIPTION

PRODUCT HIGHLIGHTS

1. Fast Throughput.

The AD7623 is a 16-bit, 1.33 MSPS, charge redistribution SAR,

fully differential analog-to-digital converter (ADC) that

operates from a single 2.5 V power supply. It contains a high

speed 16-bit sampling ADC, an internal conversion clock, an

internal reference (and buffer), error correction circuits, and

both serial and parallel system interface ports. Power consump-

tion is automatically scaled with throughput, making it ideal

for battery-powered applications. It is available in 48-lead, low

profile quad flat package (LQFP) and a lead frame chip-scale

(LFCSP_VQ) package. Operation is specified from

The AD7623 is a 1.33 MSPS, charge redistribution,

16-bit SAR ADC.

2. Superior Linearity.

The AD7623 has no missing 16-bit code.

3. Internal Reference.

The AD7623 has a 2.048 V internal reference with a

typical drift of 7 ppm/°C.

4. Single-Supply Operation.

The AD7623 operates from a 2.5 V single supply and

typically dissipates 45 mW. Its power dissipation decreases

with the throughput.

−40°C to +85°C.

5. Serial or Parallel Interface.

Versatile parallel (16- or 8-bit bus) or 2-wire serial interface

arrangement compatible with 2.5 V, 3.3 V, or 5 V logic.
