LT1678 - Dual/Quad Low Noise Rail-to-Rail Precision Op Amps

Description

The LTC®2641/LTC2642 are families of 16-, 14- and 12-bit unbuffered voltage output DACs.

These DACs operate from a single 2.7V to 5.5V supply and are guaranteed monotonic over temperature.

The LTC2641-16/LTC2642-16 provide 16-bit performance (±2LSB INL and ±1LSB DNL) over temperature.

These DACs operate from a single 2.7V to 5.5V supply and are guaranteed monotonic over temperature. The LTC2641-16/LTC2642-16 provide 16-bit performance (±2LSB INL and ±1LSB DNL) over temperature. Unbuffered DAC outputs result in low supply current of 120μA and a low offset error of ±1LSB. Both the LTC2641 and LTC2642 feature a reference input range of 2V to VDD. VOUT swings from 0V to VREF. For bipolar operation, the LTC2642 includes matched scaling resistors for use with an external precision op amp (such as the LT1678), generating a ±VREF output swing at RFB.
