Description
The AS1536/AS1537 are low-power, 12-bit, 73ksps analog-to-digital (A/D) converters specifically designed for single-supply A/D applications.
Features
- an internal 2.5V reference. As with the AS1537, the AS1536 can also be used with an external reference, which uses the input range 0V to VREF, including the positive supply range. The AS1537 consumes only 3mW (VDD = 3V) at the 73ksps maximum sampling speed. Both devices feature a low-current (0.3µA) shutdown mode, which reduces power consumption at slower throughput rates. Data accesses are made via the standard, high-speed 3-wire serial interface, which is SPI-, QSPI-, and Microwire-compatible.
