TLV1012-15YDCR

Overview

The TLV1012-15YDCR is an obsolete audio amplifier designed for high-gain two-wire electret microphones. It operates on a supply voltage of 2 V to 5 V with a fixed voltage gain of 15.6 dB. The device draws less than 180 μA of supply current and provides a signal-to-noise ratio of 60 dB (A-weighted). It features low output voltage noise of −89 dBV (A-weighted) and total harmonic distortion of 0.013%. Characterized for operation between –40°C and 85°C, it utilizes a NanoStar WCSP-4 YDC package.

Feature Summary

• Provides a fixed internal voltage gain of 15.6 dB to eliminate the need for external gain-setting components.
• Designed as a direct replacement for JFET amplifiers in small-form-factor electret microphones.
• Includes a built-in low-frequency cut-off filter to reduce wind and handling noise effects.

Applications

• Cellular phones
• Headsets
• Mobile communications devices
• Automotive accessories
• Accessory microphone products

Procurement Notes

Verify that the component status is marked as Obsolete before procurement planning. Confirm availability through lifetime-buy periods or secondary markets if required. Ensure design modifications account for the discontinuation of this specific part number to prevent future supply chain disruptions.

Selection Notes

Select this component only for legacy designs requiring a 15.6 dB gain in a four-terminal ultra-thin lead-free package. Evaluate alternative Texas Instruments audio amplifiers for new designs due to the obsolete status. Verify compatibility with existing PCB layouts intended for the YDC package form factor.

Part Context

This device belongs to the TLV1012 series of audio amplifiers specifically engineered for miniature electret microphones. It replaces traditional JFET-based solutions by offering superior linearity and temperature stability within a space-saving package suitable for integration directly inside microphone metal cans.

Replacement Considerations

The datasheet explicitly states 'Not Recommended for New Designs' and lists the status as Obsolete. No official substitute part numbers are provided in the documentation. Designers should transition to newer Texas Instruments audio amplifier families.
