Accelerometer Integrates Mic And Diff Amps

Wearing many hats, the 4290 dual-channel accelerometer integrates a microphone and differential amplifier, making it suitable for a wide range of applications. The component can also be configured as a differential dc/ac amplifier for voltage and input sensors. Features include a ±0.1% gain accuracy, ±0.01% linearity, and a frequency response of 100 kHz. Adding to its flexibility, the accelerometer also includes a user-programmable, four-pole 1 kHz, 5 kHz, 20 kHz or wideband Butterworth low-pass filter with a -24 dB/octave rolloff. Call for price.
