LTC6362HDD#PBF

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 ADC. This device draws only 1mA of supply current in active operation, and features a shutdown mode in which the current consumption is reduced to 70μA. This 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 non-inverting 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, to convert a precision sensor signal to a balanced signal for processing in noisy industrial environments. It is widely used in application such as 16-bit and 18-bit SAR ADC drivers, single-ended-to-differential conversion, low power pipeline ADC driver, differential line drivers, battery-powered instrumentation etc.
