TDA7050T/N3,112

Overview

The TDA7050T/N3,112 is a low voltage mono/stereo power amplifier designed for small radios with headphones. It operates on a supply voltage range of 1.6 to 6.0 V, featuring a total quiescent current of typically 3.2 mA at 3 V. In bridge-tied load applications with a 32 Ω load, it delivers approximately 140 mW output power at 3 V. The device includes a fixed integrated gain of 26 dB and requires no external components for basic operation.

Feature Summary

• Operates with supply voltage down to 1.6 V
• No external components required
• Very low quiescent current
• Fixed integrated gain of 26 dB

Applications

• Small radios with headphones
• Watch radios
• Pen radios
• Pocket radios

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct package type and environmental compliance status. Confirm availability through authorized NXP Semiconductors distributors as product lifecycles may change.

Selection Notes

Select this component for battery-powered audio applications requiring minimal external circuitry. Ensure the design accommodates the SO8 plastic package thermal limitations without additional heatsinking. Verify that the application strictly adheres to the specified maximum supply voltage of 6 V.
