General Instructions

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

24-bit oversampling SAR analog-to-digital converter (ADC).

The AD7767/AD7767-1/AD7767-2 combine

Large dynamic range and input bandwidth, consumes 15 mW,

10.5 mW and 8.5 mW power, respectively, included in

16-pin TSSOP package.

Ideal for ultra-low power data acquisition such as PCI and

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

Provides 24-bit resolution. Excellent SNR combination,

Wide dynamic range and excellent DC accuracy enable

AD7767/AD7767-1/AD7767-2 are ideal for measuring

Small signals vary over a wide dynamic range. This is

Particularly suitable for applications with little surface variation

The input is measured on a larger AC or DC signal. in such a

application, AD7767/AD7767-1/AD7767-2 accurate

Collect AC and DC information.

AD7767/AD7767-1/AD7767-2 include an on-board digital

Filter (with linear phase response) to remove out-of-band noise by filtering oversampled input

Voltage. The oversampling architecture also reduces the front-end

Antialiasing requirements. Additional features of the AD7767 include

SYNC/PD (sync/power-down) pin, allows

Synchronization of multiple AD7767 devices. the addition of

SDI pins provide multiple options for daisy chaining

AD7767 device.

AD7767/AD7767-1/AD7767-2 operate from a 2.5 V supply

Use a 5 V reference voltage. These devices operate over a temperature range of -40°C to +105°C.
