Product Details
The 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 1mA of supply current in active operation, and features a shutdown mode in which the current consumption is reduced to 70μA.
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, to convert 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 3mm × 3mm 8-pin leadless DFN package, and operates with guaranteed specifications over a –40°C to 125°C temperature range.
Applications
- 16-Bit and 18-Bit SAR ADC Drivers
