24 µA supply — the battery-life spec
The MAX4469ESA: The headline number for this part is the 24 µA quiescent current. In a battery-powered sensor node or a portable medical monitor that runs for months on a coin cell, that draw is what keeps the product out of the quarterly battery-replacement cycle. The trade-off is visible in the slew rate: at 0.045 V/µs, this is a slow amplifier — it will cleanly pass audio-band signals and DC-level changes, but it is not built for high-speed data acquisition or video. Pair it with a low-frequency ADC or a comparator input and the 15 mA output drive per channel is enough to swing a small relay or an LED indicator.
