Abstract
Integrated circuitry implementing amplifier circuitry, the integrated circuitry comprising first amplifier circuitry and second amplifier circuitry, the first and second amplifier circuitry being configurable as first and second single-ended amplifiers or as a differential amplifier, wherein the first amplifier circuitry comprises: a first input stage; a first half-bridge output stage having an output coupled to a first output terminal of the integrated circuitry; a first feedback path coupling a first input of the first input stage to a first sense terminal of the first amplifier circuitry; a second feedback path coupling a second input of the first input stage to a second sense terminal of the first amplifier circuitry; and a first shunt resistor coupling the output of the first half-bridge output stage to the first feedback path, wherein the second amplifier circuitry comprises: a second input stage; and a second half-bridge output stage having an output coupled to a second output terminal of the integrated circuitry, and wherein the first amplifier circuitry further comprises a second shunt resistor coupling the second feedback path to a dedicated shunt resistor terminal of the integrated circuitry, such that the second shunt resistor is directly accessible from outside the integrated circuitry.
