GENERAL DESCRIPTION
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.
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.
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
include a SYNC/PD (synchronization/power-down) pin, allowing
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.
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.
