GENERAL DESCRIPTION
The AS1536/AS1537 are low-power, 12-bit, 73ksps analog-to-digital (A/D) converters specifically designed for single-supply A/D applications. Superior AC characteristics, very low power consumption, and robust packaging make these ultra-small devices perfect for battery-powered analog-data collection devices. The integrated successive-approximation register (SAR) and a fast (1.5µs) sampling track/hold time provide an economic and highly-reliable A/D conversion solution. The AS1536/AS1537 operate from a single 2.7V to 5.25V supply. 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. Data accesses are made via the standard, high-speed 3-wire serial interface, which is SPI-, QSPI-, and Microwire-compatible. Both devices contain an internal clock, however, both devices also support an external clock for increased flexibility. The AS1536/AS1537 are available in an 8-pin SOIC-150 package.
