Product details

Supply current and thermal envelope for industrial signal chains

The MAX4128EUA+: Each amplifier draws 725 µA supply current, totalling 1.45 mA for both channels. At 5 V that is 7.25 mW quiescent — low enough for multi-channel data-acquisition boards or battery-backed sensor interfaces without a dedicated heat sink. Input offset voltage is 400 µV max, and input bias current is 50 nA — adequate for precision DC coupling in non-chopper applications.

8-MSOP package and surface-mount board integration

Supplied in a tube, the part is compatible with standard pick-and-place equipment. ROHS3 compliance is confirmed, easing regulatory acceptance for EU and global markets.

Frequently asked questions

What is the MAX4128EUA+ slew rate and what does it mean for my signal?

The slew rate is 10 V/µs. For a full-scale 5 V output swing, the output can change at 10 V/µs, so the maximum frequency before slew-rate limiting is roughly 10 V/µs / (π × 5 V) ≈ 637 kHz. Below that frequency the op-amp's small-signal bandwidth (25 MHz GBW) governs the gain.
