TWL1106PWR

Overview

The TWL1106PWR is a voice-band audio processor (VBAP) from Texas Instruments, designed for analog and digital wireless handsets. It integrates transmit encoding A/D conversion, receive decoding D/A conversion, and filtering for voice-band communications. The device operates on a 2.7-V to 3.3-V supply and accepts a 2.048-MHz master clock. It supports selectable 13-bit linear or 8-bit µ-law companded conversion modes with a 300-Hz to 3.4-kHz passband. Key features include differential microphone input with external gain setting, differential earphone output capable of driving 8-Ω to 32-Ω loads, programmable volume control in linear mode, and low power consumption of 0.03 mW in power-down mode.

Feature Summary

• Integrated VBAP performing A/D and D/A conversion with CCITT G.714 compliant filtering
• Selectable 13-bit linear or 8-bit µ-law companded conversion modes
• Differential microphone input with externally programmable gain via MICGAIN pins
• Differential earphone output driving 8-Ω to 32-Ω loads with programmable volume control in linear mode

Applications

• Analog and digital wireless handsets
• Voice-enabled terminals
• Telecommunications applications

Procurement Notes

Verify the component grade and qualification status against specific application requirements, as datasheet details are marked as unavailable in local records. Confirm the package type is 20-TSSOP and mounting style is Surface Mount. Ensure the operating temperature range meets the -40°C to 85°C specification. Check for RoHS compliance documentation if required by the target market regulations.

Selection Notes

Select this component for voice-band communication systems requiring integrated audio processing. Ensure the system provides a stable 2.048-MHz master clock input. Verify that the microphone interface can be configured with external resistors for the recommended 23.5 dB gain. Confirm that the load impedance for the earphone output falls within the 8-Ω to 32-Ω range for optimal performance.

Part Context

The TWL1106 belongs to the VBAP™ series of voice-band audio processors. It is manufactured by Texas Instruments and is housed in a 20-TSSOP package with a width of 4.40 mm. The device is designed to replace discrete audio processing solutions by integrating amplifiers, filters, and converters into a single low-profile IC.
