ZHCSLZ5D October 2020 – December 2023 OPA3S328
PRODUCTION DATA
The OPA3S328 amplifiers can be placed into a power-down state independently. When in this power-down state, the output of the amplifier is high-impedance (> 1 GΩ) and the amplifier consumes 30 µA of quiescent current.
Power down is controlled through digital logic pins SELA0, SELA1, SELB0 and SELB1, which require a minimum 1.8 V between V+ and GND to provide functionality. For guidance on programming the device for power down, see the logic table in Table 4-3.
