70 kHz GBW, 5 µA supply — the low-power signal chain choice
The ROHM BU7245HFV-TR is a single-channel general-purpose CMOS op-amp designed for applications where supply current is the primary constraint. The rail-to-rail output stage swings within millivolts of both supply rails, preserving dynamic range at the low 1.8 V minimum supply. Input bias current is 1 pA, so it won't load high-impedance sources like pH probes or pyroelectric sensors.
Rail-to-rail output means the amplifier can swing close to the supply rails, useful when the ADC reference is the same supply. Input offset voltage is 1 mV typical, which stacks directly into the error budget for precision DC measurements.
Package and temperature grade
Housed in a 5-pin SOT-665 (also designated 5-HVSOF), the package is a surface-mount, leadless footprint.
Lifecycle and sourcing posture
It is RoHS3 compliant.
