PAA-SAMPLE KIT V2 Sonitron, Audio Amplifier Module Printed Circuit Board for PAA Sample Kit

Sonitron PAA Piezo Ceramic Design Kit

The PAA piezo ceramic audio design sample kit from Sonitron includes four different piezo audio amplifiers and is ideal for experimenting with the included speaker. The kit consists of a SPS-6555-03 speaker built into a small plastic case, with four PAA amplifiers
PAA-LT3469-01, PAA-MAX9788-01, PAA-LM4960SQ-02, PAA-StepUpBTL-01.

PAA-LT3469-01 Audio Amplifier

The PAA-LT3469-01 amplifier is a piezo microactuator driver with boost regulator. From a 5 V or 12 V supply, it can drive outputs up to 33 V, and capacitive loads of 5 nF to 300 nF. An internal regulator generates a boosted supply voltage, and slew rate is limited by the maximum output current. This amplifier features high switching frequency and an internal Schottky diode. The PAA-LT3469-01 amplifier has a typical unloaded gain of 30000 and compact external components.

PAA-MAX9788-01 Audio Amplifier

The PAA-MAX9788-01 amplifier features low power consumption and a maximum output of 20 V pp. This piezo amplifier has an integrated charge pump power supply and offers fully differential outputs and inputs. This class G amplifier manages capacitive loads up to 1 μF.

PAA-LT3469-01 Audio Amplifier

Featuring a great sound output and compact design, the PAA-LT3469-01 piezo amplifier offers an integrated step up converter and bridge tied load. For a load of 600 nF, the amplifier reached 24 V pp.

PAA-StepUpBTL-01 Audio Amplifier

The PAA-StepUpBTL-01 amplifier is designed for a loud audio sound. This piezo amplifier is constructed from a bridge tied load circuit and a step up converter circuit. With an input voltage range of 5 V to 25 V, the PAA-StepUpBTL-01 offers a fixed amplification ratio of ±90.
