The LTC1562 is a low noise, low distortion continuous-time filter with ±5V single supply or ±5V/±10V dual supply, 10kHz to 150kHz center frequency, 4 independent 2nd order filter blocks, resistor-programmable center frequency, Q and gain.
The LTC1562 is a low noise, low distortion continuous-time filter with rail-to-rail inputs and outputs. It features four independent 2nd order filter blocks that can be cascaded in any combination, such as one 8th order or two 4th order filters. Unlike most monolithic filters, no clock is needed for operation.
Each block's response (lowpass, bandpass, highpass) is programmed with three external resistors for center frequency, Q, and gain. The device supports single or dual supply voltages from 5V to 10V total and includes a zero-power shutdown mode.
| Center Frequency Range | 10kHz to 150kHz |
