`Preamplifier has a high open-loop gain (VGO = 73 dB).
`Preamplifier requires no NF capacitor.
`Virtual ground capacitor can be 1 F or less. (Lower impedance is achieved by having a VREF amplifier built in.)
`Ripple filter requires no capacitor for preventing oscillation.
`Powerful output is obtained in low boost output (Po = 21 mW/VCC = 1.2 V, f = 100 Hz).
`A high-frequency cutoff capacitor is built into the preamplifier and power amplifier inputs; anti-buzz provision.
