Differential Amplifier Drives 18-Bit ADCs

May 10, 2012
The LTC6362 low power, fully differential amplifier from Linear Technology, can drive high precision 16- and 18-bit SAR ADCs at a 1mA supply current.
The LTC6362 low power, fully differential amplifier from Linear Technology, can drive high precision 16- and 18-bit SAR ADCs at a 1mA supply current. With 200 µV max input offset voltage and 3.9 nV/√Hz input-referred noise, it is suited for precision industrial and data acquisition applications. The amplifier has an output common-mode pin with a 0.5 V to 4.5 V range, and 18-bit settling time of 550 ns with an 8 V P-P output step, for use with ADCs such as the LTC2379-18 in multiplexed input and control loop applications. This device’s digital gain compression, combined with the rail-to-rail output stage of the LTC6362, eliminates the need for a negative supply rail, thereby minimizing power consumption. The LTC6362 is available in MSOP-8 and 3mm x 3mm DFN packages, with specifications over the 0°C to 70°C, -40°C to 85°C and -40°C to 125°C temperature ranges. Prices start at $1.59 each/1,000.
