The LM4871MM/NOPB is a mono bridged Audio Power Amplifier capable of delivering 3W of continuous average power into a 3R load with less than 10% THD when powered by a 5V power supply. To conserve power in portable applications, the LM4871's micropower shutdown mode (IQ = 0.6µA, typical) is activated when VDD is applied to the shutdown pin. Boomer audio power amplifier is designed specifically to provide high power, high fidelity audio output. It requires few external components and operates on low supply voltages from 2.0 to 5.5V. Since the LM4871 does not require output coupling capacitors, bootstrap capacitors or snubber networks, it is ideally suited for low-power portable systems that require minimum volume and weight. Additional LM4871 features include thermal shutdown protection, unity-gain stability and external gain set.

• No output coupling capacitors, bootstrap capacitors or snubber circuits are necessary
• Unity-gain stable
• External gain configuration capability
• Pin compatible with LM4861
• 0.6µA (typical) Shutdown current
• Green product and no Sb/Br

The LTC1540IMS8#PBF is an ultralow nano-power single Comparator with built-in reference. The comparator features include less than 0.6µA supply current over the commercial temperature range, a 1.182V±2% reference, programmable hysteresis and TTL/CMOS outputs that sink and source current. The reference output can drive a bypass capacitor of up to 0.01µF without oscillation. The comparator operates from a single 2 to 11V supply or a dual ±1 to ±5.5V supply. Comparator hysteresis is easily programmed by using two resistors and the HYST pin. The comparator input operates from the negative supply to within 1.3V of the positive supply. The comparator output stage can continuously source up to 40mA. By eliminating the cross-conducting current that normally occur when the comparator changes logic states, power supply glitches are eliminated.
