LTC6362 Differential Amplifier

Precision, low-power, rail-to-rail input/output differential op amp/SAR ADC driver from Analog Devices

Image of Analog Devices' LTC6362 Differential AmplifierAnalog Devices' LTC6362 is a low-power, low-noise differential op amp with rail-to-rail input and output swing that has been optimized to drive low power SAR ADCs. The LTC6362 draws only 1 mA of supply current in active operation, and features a shutdown mode in which the current consumption is reduced to 70 µA.

The amplifier may be configured to convert a single ended input signal to a differential output signal, and is capable of being operated in an inverting or noninverting configuration.

Low offset voltage, low-input bias current, and a stable, high-impedance configuration make this amplifier suitable for use, not only as an ADC driver but also earlier in the signal chain, in converting a precision sensor signal to a balanced (differential) signal for processing in noisy industrial environments.

The LTC6362 is available in an 8-lead MSOP package and also in a compact 3 mm x 3 mm 8-pin leadless DFN package, operating with guaranteed specifications over a -40°C to +125°C temperature range.
