Related Devices The AD5061, a member of the Analog Devices, Inc., nanoDAC Part No. Description family, is a low power, single 16-bit buffered voltage-out DAC AD5062 2.7 V to 5.5 V, 16-bit nanoDAC converter, that operates from a single 2.7 V to 5.5 V supply. The device 1 LSB INL, SOT-23 AD5063 2.7 V to 5.5 V, 16-bit nanoDAC converter, offers a relative accuracy specification of 4 LSB and operation 1 LSB INL, MSOP is guaranteed monotonic with a 1 LSB DNL specification. The AD5040/AD5060 2.7 V to 5.5 V, 14-bit/16-bit nanoDAC converter, device uses a versatile 3-wire serial interface that operates at 1 LSB INL, SOT-23 clock rates up to 30 MHz, and is compatible with standard SPI, QSPI, MICROWIRE, and DSP interface standards. The reference for the AD5061 is supplied from an external V pin. A reference REF PRODUCT HIGHLIGHTS buffer is also provided on-chip. The device incorporates a 1.
