High output current allows low load impedances to be driven. The TS921 exhibits a very low noise, low distortion, low offset and high ouput current capability making this device an excellent choice for high quality, low voltage or battery operated audio systems. The device is stable for capacitive loads up to 500pF. Part Number TS921I Temperature Range -40, +125oC Package N • D • P • PIN CONNECTIONS (top view) N.C.
