Description
The MAX9725E evaluation kit (EV kit) is a fully assembled and tested printed-circuit board (PCB) that uses the MAX9725E IC to drive a stereo headphone in portable applications. The MAX9725E is a low-power stereo headphone amplifier with adjustable gain and DirectDrive® outputs. Maxim's DirectDrive technology eliminates the need for bulky DC blocking capacitors at the output of the amplifier.
The EV kit is configured for a -1.82V/V gain and is designed to operate from a 0.9V to 1.8V DC power supply. The EV kit is capable of delivering up to 20mW per channel into a 32Ω load and achieves 0.006% THD+N.
The MAX9725E EV kit can also be used to evaluate the MAX9725A, MAX9725B, MAX9725C, or MAX9725D fixed-gain amplifiers. Contact Maxim for free samples of the MAX9725A, MAX9725B, MAX9725C, or MAX9725D. See the Part Selection Table in the full data sheet for IC ordering information. The MAX9725_ IC temperature range is -40°C to +85°C.
