LTC2050/LTC2050HV APPLICATIONS INFORMATION Shutdown output multiplied by the closed loop gain of the op amp. To reduce this form of clock feedthrough, use smaller The LTC2050 includes a shutdown pin in the 6-lead valued gain setting resistors and minimize the source SOT-23 and the SO-8 version. When this active low pin resistance at the input. If the resistance seen at the inputs is high or allowed to float, the device operates normally. is less than 10k, this form of clock feedthrough is less When the shutdown pin is pulled low, the device enters than 1µV input referred at 7.5kHz, or less than the shutdown mode; supply current drops to 3µA, all clock- RMS amount of residue clock feedthrough from the first form ing stops, and both inputs and output assume a high described above. impedance state.
