Class-D Audio Power Amplifier – 2 × 25W

The AD1994 class-D Amplifier integrates a stereo Modulator and stereo bridge-tied" load (BTL) power stage onto a single die capable of delivering 50W of continuous power without a heat sink. The new Modulator architecture uses a patented dynamic hysteresis algorithm to achieve audiophile performance (THD 105 dB) without compromising efficiency. The closed-loop architecture and continuous-time Modulator front-end achieve a PSRR > 65 dB, and the stereo BTL power stage requires only a single supply that CAN operate over a wide voltage range. The Modulator in the AD1994. designed to minimize radiated and conducted EMI and RF emissions, CAN optionally be used to drive external power devices to achieve arbitrarily high output power.
