The LTC2632 and LTC2633 DACs from Linear Technology are suitable for industrial, automotive, portable communications and automotive test equipment applications. The dual 12, 10, and 8bit rail-to-rail DACs feature serial peripheral interface for the LTC2632 series and I2C interface for LTC2633 series. The DACs feature a small solution size, making them suitable for trimming applications. They offer good DC performance with a 12bit INL of ±1 least significant bit, ±5mV offset error and ±0.8% FSR gain error. The DACs also deliver a settling time of 4.4µs and a glitch impulse of 2.8nV/s. Each dual DAC integrates a 10ppm/°C reference into a eight-lead 3x3mm TSOT-23 package.
The DACs feature a full-scale output range of 2.5V (-L) or 4.096V (-H) making them suitable for 3 or 5V systems. They also offer zero or mid-scale power-on reset options. The LTC2633-L also offers a high impedance output option, making it suitable for power supply margining applications.
