MAX40023/MAX40024 Low-Noise, Low-Power, Low-Bias-Current Amplifiers General Description Benefits and Features The MAX40023/MAX40024 are single and dual amplifiers Ultra-Low <1pA Input Bias Current optimized for power-sensitive applications that require low Low 17A Quiescent Current (per Op Amp) noise and very low-leakage input current (bias current). Low 32nV/Hz Input-Voltage Noise Internal EMI Rejection The MAX40023/MAX40024 amplifiers consume less than Supply Voltage Range: 1.6V to 3.6V 17A (typ) of supply current per channel, but also feature Power-Saving Shutdown Mode incredibly low noise as low as 32nV/Hz. The input bias Available in 6-Bump WLP and 6-Pin SOT23 (Single) current is <1pA at room temperature. and 9-Bump WLP and 10-Pin TDFN (Dual) These amplifiers are available in a space-saving, 6-bump wafer-level package (WLP) with a 0.4mm bump pitch (sin- Ordering Information appears at end of data sheet. gle), 9-bump WLP (dual), 6-pin SOT23 (single), and 10-pin TDFN (dual). They are designed for use as a sen- sor interface in wearable medical and industrial sensor ap- plications. The MAX40023/MAX40024 amplifiers operate from a 1.6V to 3.6V power supply voltage and are specified over the -40C to +125C operating temperature range.
