24-Bit, 8.5 mW, 109 dB,

128/64/32 kSPS ADCs

AD7767

FEATURES

GENERAL DESCRIPTION

Oversampled successive approximation (SAR) architecture

High performance ac and dc accuracy, low power

115.5 dB dynamic range, 32 kSPS (AD7767-2)

112.5 dB dynamic range, 64 kSPS (AD7767-1)

109.5 dB dynamic range, 128 kSPS (AD7767)

−118 dB THD

The AD7767/AD7767-1/AD7767-2 are high performance

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

The AD7767/AD7767-1/AD7767-2 combine the benefits of a

large dynamic range and input bandwidth, consuming 15 mW,

10.5 mW, and 8.5 mW power, respectively, all contained in a

16-lead TSSOP package.

Exceptionally low power

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

USB-based systems), the AD7767/AD7767-1/AD7767-2

provide 24-bit resolution. The combination of exceptional SNR,

wide dynamic range, and outstanding dc accuracy make the

AD7767/AD7767-1/AD7767-2 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 AD7767/AD7767-1/AD7767-2 accurately

gather both ac and dc information.

8.5 mW, 32 kSPS (AD7767-2)

10.5 mW, 64 kSPS (AD7767-1)

15 mW, 128 kSPS (AD7767)

High dc accuracy

24 bits, no missing codes (NMC)

INL: 3 ppm (typical), 7.6 ppm (maximum)

Low temperature drift

Zero error drift: 15 nV/°C

Gain error drift: 0.0075% FS

On-chip low-pass FIR filter

The AD7767/AD7767-1/AD7767-2 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 AD7767 include a

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

(synchronization/power-down) pin, allowing the

Synchronization of multiple devices

Daisy chain capability

Power-down function

synchronization of multiple AD7767 devices. The addition of

an SDI pin provides the option of daisy chaining multiple

AD7767 devices.

Temperature range: −40°C to +105°C

The AD7767/AD7767-1/AD7767-2 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
