Each of the four channels draws 1 µA of supply current.
At 1 µA per amplifier, the TLV2244IDR draws 600× less supply current than a single-channel part that draws 600 µA per channel. The trade-off is bandwidth: 5.5 kHz GBW and 0.002 V/µs slew rate.
No. The LM324 is a much faster, higher-power quad op-amp (typically 1 MHz GBW, 0.5 V/µs slew rate, 500 µA per channel). The TLV2244IDR's 5.5 kHz GBW and 0.002 V/µs slew rate are too slow for most LM324 applications. The TLV2244IDR is a micropower part for low-frequency, battery-operated designs, not a general-purpose swap.
