Power Amp Design Rail to Rail Operational Amplifier PAD127

The PAD127 rail to rail operational amplifier is constructed with surface mount components to provide a cost effective solution for many industrial applications where it is important to obtain a maximum output signal with limited supply voltages. The PAD127 outperforms much more expensive hybrid component amplifiers or rack-mount amplifiers in a footprint only 80mm square. User selectable external compensation tailors the amplifier’s response to the application requirements. Four-wire programmable current limit is built-in, but the PAD127 is compatible with the external PAD121 current limit accessory module as well. The PAD127 also features a substrate temperature reporting analog output and over-temp shutdown. The amplifier circuitry is built on an insulated metal substrate mounted to an integral heat sink and fan assembly. No BeO is used in the PAD127. The resulting module is a small, high performance turn-key solution for many industrial applications.
