Overview
The TWL1110PBSR is a Voice-Band Audio Processor (VBAP) manufactured by Texas Instruments, designed for analog and digital wireless handsets. It operates on a single 2.7 V to 3.3 V supply and features two differential microphone inputs with programmable gain. The device includes differential and single-ended earphone outputs capable of driving loads down to 8 Ω. It supports PCM clock rates of 128 kHz and 2.048 MHz, offers 15-bit linear or 8-bit companded data modes, and integrates an I²C control interface.
Feature Summary
- Integrated voice-band audio processing with transmit/receive paths and sidetone
- Two differential microphone inputs and dual earphone outputs (differential/single-ended)
- Programmable DTMF tone generator with selectable resolutions
- I²C serial interface for register configuration and power management
Applications
- Analog wireless handsets
- Digital wireless handsets
- Telecommunications equipment
Procurement Notes
Verify the PBSR suffix indicates bulk packaging rather than tape-and-reel. Confirm the component meets industrial temperature requirements (-40°C to +85°C). Ensure the design accounts for the specific 32-TQFP pinout and power sequencing requirements detailed in the datasheet.
Selection Notes
Select this component for applications requiring integrated voice-band processing with low-power operation. Compare against pin-compatible alternatives like the TWL1102 or TWL1109 if different feature sets are needed. Verify that the required I²C address and register map align with the host controller software.
Part Context
The TWL1110 belongs to Texas Instruments' VBAP family, serving as an analog-digital interface for voice signals. It combines codecs and filters to meet telephony standards. This specific part number denotes the TQFP package variant, distinct from the MicroStar Junior BGA option available for the same core functionality.
Replacement Considerations
Pin-compatible replacements include the TWL1102, TWL1103, and TWL1109 devices for TQFP packages. Verify functional equivalence regarding gain ranges and filter characteristics before substitution.
