24-Bit, 8.5 mW, 109 dB,

128 kSPS/64 kSPS/32 kSPS ADCs

AD7766

FEATURES

GENERAL DESCRIPTION

Oversampled successive approximation (SAR) architecture

High performance ac and dc accuracy, low power

115.5 dB dynamic range, 32 kSPS (AD7766-2)

112.5 dB dynamic range, 64 kSPS (AD7766-1)

109.5 dB dynamic range, 128 kSPS (AD7766)

−112 dB THD

The AD7766/AD7766-1/AD7766-2 are high performance,

24-bit, oversampled SAR analog-to-digital converters (ADCs).

The AD7766/AD7766-1/AD7766-2 combine the benefits of a

large dynamic range and input bandwidth, consuming 15 mW,

10.5 mW, and 8.5 mW power, respectively, and are contained in

a 16-lead TSSOP package.

Exceptionally low power

Ideal for ultralow power data acquisition (such as PCI- and USB-

based systems), the AD7766/AD7766-1/AD7766-2 provide 24-bit

resolution. The combination of exceptional SNR, wide dynamic

range, and outstanding dc accuracy make the AD7766/AD7766-1/

AD7766-2 ideally suited for measuring small signal changes over a

wide dynamic range. This is particularly suitable for applications

where small changes on the input are measured on larger ac or

dc signals. In such an application, the AD7766/AD7766-1/

AD7766-2 accurately gather both ac and dc information.

8.5 mW, 32 kSPS (AD7766-2)

10.5 mW, 64 kSPS (AD7766-1)

15 mW, 128 kSPS (AD7766)

High dc accuracy

24 bits, no missing codes (NMC)

INL: 6 ppm (typical), 15 ppm (maximum)

Low temperature drift

Zero error drift: 15 nV/°C

Gain error drift: 0.4 ppm/°C

The AD7766/AD7766-1/AD7766-2 include an on-board digital

filter (complete with linear phase response) that acts to elimi-

nate out-of-band noise by filtering the oversampled input voltage.

The oversampled architecture also reduces front-end antialias

requirements. Other features of the AD7766/AD7766-1/AD7766-2

On-chip low-pass FIR filter

Linear phase response

Pass-band ripple: 0.005 dB

Stop-band attenuation: 100 dB

2.5 V supply with 1.8 V/2.5 V/3 V/3.6 V logic interface options

Flexible interfacing options

SYNC PD

include a

(synchronization/power-down) pin, allowing

Synchronization of multiple devices

Daisy-chain capability

Power-down function

the synchronization of multiple AD7766/AD7766-1/AD7766-2

devices. The addition of an SDI pin provides the option of daisy

chaining multiple AD7766/AD7766-1/AD7766-2 devices.

Temperature range: −40°C to +105°C

The AD7766/AD7766-1/AD7766-2 operate from a 2.5 V supply

using a 5 V reference. The devices operate from −40°C to +105°C.

APPLICATIONS

Low power PCI/USB data acquisition systems

Low power wireless acquisition systems

Vibration analysis

Instrumentation

High precision medical acquisition
