DAC161S055 www.ti.com SNAS503B – NOVEMBER 2010 – REVISED JANUARY 2012 DAC161S055 Precision 16-Bit, Buffered Voltage-Output DAC Check for Samples: DAC161S055 FEATURES 1 2 16-bit DAC with a Two-buffer SPI Interface Asynchronous Load DAC and Reset Pins Compatibility with 1.8V Controllers Buffered Voltage Output with Rail-to-Rail Capability Wide Voltage Reference Range of +2.5V to VA Wide Temperature Range of −40°C to +105°C Packaged in a 16-pin WQFN APPLICATIONS Process Control Automatic Test Equipment Programmable Voltage Sources Communication Systems Data Acquisition Industrial PLCs Portable Battery Powered Instruments KEY SPECIFICATIONS Resolution (Specified Monotonic) 16 bits INL ±3 LSB (max) Very Low Output Noise 120 nV/√Hz (typ) Glitch Impulse 7 nV-s (typ) Output Settling Time 5 µs (typ) Power Consumption 5.5 mW at 5.25 V (max) DESCRIPTION The DAC161S055 is a precision 16-bit, buffered voltage output Digital-to-Analog Converter (DAC) that operates from a 2.7V to 5.25V supply with a separate I/O supply pin that operates down to 1.7V. The onchip precision output buffer provides rail-to-rail output swing and has a typical settling time of 5 µsec. The external voltage reference can be set between 2.5V and VA (the analog supply voltage), providing the widest dynamic output range possible. The 4-wire SPI compatible interface operates at clock rates up to 20 MHz. The part is capable of Diasy Chain and Data Read Back. An on board power-o...
