AD1990ACPZRL

Overview

The AD1990ACPZRL is a two-channel, bridge-tied load (BTL) switching audio power amplifier with an integrated Sigma-Delta modulator. It accepts single-ended analog inputs and converts them to switching waveforms for direct speaker drive. The device operates from a power supply range of 8 V to 12 V, while the analog and digital logic utilize a 5 V supply. Key performance metrics include a signal-to-noise ratio of 102 dB and total harmonic distortion plus noise of 0.003% at 1 W output into a 6 Ω load.

Feature Summary

• Integrates stereo Sigma-Delta modulation and power stage for high-efficiency amplification
• Provides 65 dB pop noise suppression during mute transitions
• Includes short-circuit and overtemperature protection circuits
• Features EMI-optimized modulation architecture

Applications

• Advanced televisions
• Compact multimedia systems
• Minicomponents
