The 4 mA supply current is a reasonable trade-off for the bandwidth — it is not a micropower part, but it will not dominate a mixed-signal rail budget either.
DC precision: 500 µV offset and 500 nA bias current
Input offset voltage is rated at 500 µV, and input bias current at 500 nA. These are moderate figures — fine for audio or control loops where a few millivolts of DC error can be trimmed or tolerated, but not the right choice for a precision integrator or a 12-bit data acquisition front end without auto-zero. If your design needs sub-100 µV offset or picoamp bias, look at a JFET or CMOS input stage instead.
Package, temperature grade, and supply range
Housed in an 8-pin SOIC (0.209" body width, 5.30 mm), surface-mount only. The single 38 mA output per channel can drive a headphone or a line-level load, but not a speaker directly.
