AS1528/AS1529
Datasheet - Application Information
9 Application Information
Automatic Shutdown Mode
With CNVST low, the AS1528/AS1529 default to automatic shutdown (< 0.2μA) mode after power-up and between
conversions. After detecting a rising edge of CNVST, the AS1528/AS1529 powers up, sets DOUT low, and enters
track mode.
After detecting a falling edge of CNVST, the device enters hold mode and begins the conversion. A maximum of 3.7μs
later, the device completes conversion, enters shutdown, and MSB is available at DOUT.
External Reference
An external reference is required for the AS1528/AS1529. Use a 4.7μF bypass capacitor for best performance. The
reference input structure allows a voltage range of +1V to V
DD
+ 50mV.
Performing a Conversion
1. Use a general-purpose I/O line on the CPU to hold CNVST low between conversions.
2. Drive CNVST high to acquire AIN1(AS1529) or unipolar mode (AS1528). To acquire AIN2 (AS1529) or bipolar
mode (AS1528), drive CNVST low and high again.
3. Hold CNVST high for 1.4μs.
4. Drive CNVST low and wait approximately 3.7μs for conversion to complete. After 3.7μs, the MSB is available
at DOUT.
5. Activate SCLK for a minimum of 12 rising clock edges. DOUT transitions on SCLK’s falling edge and is avail-
able in MSB-first format. Observe the SCLK to DOUT valid timing characteristic. Clock data into the μP on
SCLK’s rising edge.
Standard Interface Connections
The AS1528/AS1529 serial interface is fully compatible with SPI, QSPI, and MICROWIRE. If a serial interface is avail-
able, establish the processor’s serial interface as a master so that the CPU generates the serial clock for the AS1528/
AS1529 and select a clock frequency up to 8MHz.
SPI and Microwire Interface
When using an SPI (
Figure 22
) or Microwire interface (
Figure 23
), set CPOL = CPHA = 0. Two 8-bit readings are nec-
essary to obtain the entire 10-bit result from the AS1528/AS1529. DOUT data transitions on the serial clock’s falling
edge and is clocked into the processor on SCLK’s rising edge. The first 8-bit data stream contains the first 8-bits of
DOUT starting with the MSB. The second 8-bit data stream contains the remaining four result bits. DOUT then goes
high impedance.
