LTC1663CS5#TRPBF

The Analog Devices Inc. LTC1663CS5#TRPBF is a 10-bit voltage output digital-to-analog converter (DAC) designed for micropower applications. It offers true buffered rail-to-rail output voltage capability and operates from a single supply voltage ranging from 2.7V to 5.5V.

This DAC features a selectable reference, allowing the use of either the supply voltage or an internal bandgap reference, which sets the full-scale output voltage range to 2.5V. The interface is a simple 2-wire serial compatible with SMBus and I2C, enabling communication with multiple devices. The internal data registers are double buffered for simultaneous updates.

The LTC1663CS5#TRPBF includes a low current power-down mode for power-conscious systems and a power-on reset function that ensures the DAC output is at 0V upon initial power application. It is supplied in a compact SOT-5 package, suitable for surface mount technology (SMT) applications.

Key electrical specifications include a resolution of 10 bits, 1 channel, and a settling time of 30 µs. It has a low operating supply current of 75 µA and a power dissipation of 0.625 mW. The differential nonlinearity (DNL) is 0.2 LSB and integral nonlinearity (INL) is 0.5 LSB.
