CD3269A0YZPR Description

Short technical summary and product information.

The Texas Instruments CD3269A0YZPR is an active audio interface transmitter designed for specially enabled audio interfaces, including iPhone and iPad compatibility. It supports two operating modes: button mode and tone mode.

 

In button mode, the device does not support a microphone but passes DC voltage from an external switch-resistor network to the MIC pin for external voltage measurement. In tone mode, it supports a microphone and senses button presses via an external switch-resistor network. Tone mode generates ultrasonic signals superimposed on the system MICBIAS line via the TONE pin driver output, controlling audio functions when connected to a compatible interface. The input DC bias level on the MIC pin selects between button and tone modes. During tone mode, the CD3269A0YZPR can also control or bias an external MEMS microphone module.

 

This transmitter features low quiescent current, drawing 3µA in button mode and 110µA in tone mode. It is housed in a miniature DSBGA (YZP) package with an ESD performance of 2000V for the Human Body Model and 500V for the Charged Device Model. The operating temperature range is from -40°C to 85°C.
