 软件简介 |
The AD7190 is a low noise, complete analog front end for high
precision measurement applications. It contains a low noise, 24-
bit Σ-Δ ADC. The on-chip low noise gain stage means that
signals of small amplitude can be interfaced directly to the
ADC.
The device can be configured to have two differential inputs or
four pseudo-differential inputs. The device can be operated
with either the internal clock or an external clock. The output
data rate from the part can be varied from 4.7 Hz to 4.8 kHz.
The device can be operated with a sinc3 or a sinc4 digital filter.
At the lower update rates, the sinc3 is useful to optimize the
settling time. The benefit of the sinc4 at low update rates is the
superior 50 Hz/60 Hz rejection. At the higher update rates, the
sinc4 filter gives best noise performance. For applications that
require all conversions to be settled, the AD7190 includes a
zero-latency feature.
The part operates with a power supply from 3 V to 5.25 V. It
consumes a current of 6 mA. It is housed in a 24-lead TSSOP
package.
