8 Detailed Description
The AS1526/AS1527 analog-to-digital converters have two modes of operation:
Normal A/D Conversion Mode – Pulling pin SHDNN high or leaving it open puts the device into normal A/D conversion mode.
Shutdown Mode – Pulling pin SHDNN low shuts the device down and reduces supply current below 2μA (V
DD
≤
3.6V).
Note:
Pulling pin CSN low starts a conversion. The conversion result is available at pin DOUT in unipolar serial format
(see Timng and Con-
trol on page 11)
.
Figure23
shows a basic configuration for the AS1526/AS1527. The integrated input track/hold circuitry and a successive-approximation register
(SAR) circuitry convert analog input signals to a digital 10-bit output. No external-hold capacitor is needed for the track/hold circuit.
The devices convert analog input signals in the 0V to V
REF
range in 13μs (includes track/hold acquisition time).
The AS1526 internal reference is trimmed to 2.5V; the AS1527 requires an external reference. Both devices can accept external reference
voltages from1.0V to V
DD
. The serial interface requires only three digital lines (at pins SCLK, CSN, and DOUT) and provides a simple
mcroprocessor interface.

8.1 Analog Input
Figure24
illustrates the integrated comparator sampling architecture. The full scale input voltage is set by the voltage at pin REF.
Figure 24. Equivalent Input Circuit
The devices’ input tracking circuitry has a 2.5MHz small-signal bandwidth, thus it is possible to under-sample (digitize high-speed transient
events) and measure periodic signals with bandwidths exceeding the devices’ sampling rate.
Note:
Anti-aliasing filtering should be used to avoid aliasing of unwanted high-frequency signals into the bandwidth of interest.
