1 / 2 page AS1526, AS1527 10-Bit, Single Supply, Low-Power, 73ksps A/D Converters austriamicrosystems Produ ct Brief www.austriamicrosystems.com Revision 1.02 1 - 2 1 General Description The AS1526/AS1527 are low-power, 10-bit, 73ksps ana- log-to-digital (A/D) converters specifically designed for single-supply A/D applications. Superior AC characteris- tics, very low power consumption, and robust packaging make these ultra-small devices perfect for battery-pow- ered 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 AS1526/AS1527 operate from a single 2.7 to 3.6V supply. The AS1527 requires an external reference, using less power than the AS1526, however, the AS1526 features an internal 2.5V reference. As with the AS1527, the AS1526 can also be used with an external reference, which uses the input range 0V to VREF, including the positive supply range. The AS1527 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. Both devices contain an internal clock, however, both devices also support an external clock for increased flexibility. The AS1526/AS1527 are available in an 8-pin SOIC-150 package. Figure 1.
