产品概况
The LTC6373 is a precision instrumentation amplifier with fully differential outputs which includes a highly-matched internal resistor network to achieve excellentCMRR and extremely low gain error, gain drift, and gain nonlinearity. The user can easily program the gain to one of seven available settings through a 3-bit parallel interface (A2 to A0). The 8th state puts the part in shutdown which reduces the current consumption to 250μA.
The LTC6373 features fully differential outputs to drivehigh performance, differential-input ADCs. The output common mode voltage is independently adjustable via the VOCM pin. The combination of high impedance inputs, DC precision, low noise, low distortion, and high-speed differential ADC drive makes the LTC6373 an ideal candidate for data acquisition systems.
The LTC6373 is available in a 12-lead 4mm × 4mm DFN package and is fully specified over the 0°C to 85°C temperature range.
