Dual supply voltage provides higher efficiency and better power ripple rejection. The APA2176/2176A is designed with ground-reference output and no need the output capacitors for DC blocking. The advantages of eliminating the output capacitor are saving the cost, PCB’s space, and component height. The built-in gain setting can minimize the external component counts and save the PCB space. High PSRR provides increased immunity to noise and RF rectification. In addition to these features, a fast start-up ti.
