NCS2632
NOCAP], Pop-Free, 3 VRMS
Audio Line Driver with
Adjustable Gain
The NCS2632 is a popâfree stereo line driver. It uses
ON Semiconductorâs patented NOCAP technology which allows the
elimination of the external DCâblocking capacitors by providing
groundâreferenced outputs through the generation of an internal
negative supply rail. The device can drive 3 VRMS into a 600 W load at
5 V power supply. By eliminating the two external heavy coupling
capacitors, the NOCAP approach offers significant space and cost
savings compared to similar audio solutions.
The NCS2632 has differential inputs and is available with an
external adjustable gain ranging from ±1 V/V to ±10 V/V. The gain is
adjusted with external resistors. The device can also be configured as a
2nd order low pass filter to complement DACâs and SOC converters.
In addition to the NOCAP architecture, it contains specific circuitry to
prevent âPop & Clickâ noise from occurring during Enable /
Shutdown transitions. The Signal-to-Noise Ratio reaches 105 dB,
offering high fidelity audio sound. The NCS2632 exhibits a high
power supply rejection with a typical value of 90 dB. This device also
features an UnderâVoltage Protection (UVP) function which can be
adjusted using an external resistor bridge. The device is available in a
TSSOPâ14 package.
