ZYMICRO ZYA5061T

The ZYA5061T is a low-power, single-channel, 16-bit buffered voltage output DAC offering 1 LSB INL and 1 LSB DNL relative accuracy, with a dedicated reference pin. The ZYA5061T supports single-supply operation from 4.5 V to 5.5 V and provides ±1 LSB differential accuracy. These devices feature a versatile 3-wire, low-power, Schmitt trigger serial interface capable of operating at clock rates up to 50 MHz, compatible with standard SPI, QSPI, MICROWIRE, and DSP interface standards. An integrated reference voltage buffer and output amplifier are provided on-chip. A built-in power-on reset circuit ensures the DAC output powers up to zero-scale or midscale and remains at that level until a valid write operation is performed on the device. The total unadjusted error of the device is less than 2πM V.
