voice switched speaker-phone circuit.
* Attenuator gain range: 52dB (between Transmit and Receive) * For line-powered applications : 3~6.5V low voltage operation * For improved sensitivity :4-point signal sen.
: 3~6.5V low voltage operation * For improved sensitivity :4-point signal sensing * For Transmit and Receive paths: back.
As a voice switched speaker-phone integrated circuit, the UTC MC34118 includes the necessary amplifiers, attenuators, level detectors and control algorithm.
To form the UTC MC34118’s internal circuit, there is an internal microphone amplifier with ad.
