ELECTRICAL CHARACTERISTICS (continued)

MC13109A

Speaker Amplifier/SP Mute

The Speaker Amplifier is an inverting rail–to–rail

operational amplifier. The non–inverting input terminal is

connected to the internal VB half supply reference. External

resistors and capacitors are used to set the gain and

frequency response. The “SA In” input is ac coupled.

(Test Conditions: VCC = 2.6 V, TA = 25°C, fin = 1.0 kHz, External Resistors Set for Gain of 1.)

Mic Amplifier

The Mic Amplifier is an inverting rail–to–rail output

operational amplifier with the non–inverting input terminal

connected to the internal VB half supply reference. External

resistors and capacitors are connected to set the gain and

frequency response. The “Tx In” input is ac coupled.

(Test Conditions: VCC = 2.6 V, TA = 25°C, fin = 1.0 kHz, External Resistors Set for Gain of 1.)
