Specifications and operating details
The following points were extracted from the PDF text. Check the associated conditions, notes and limits in the complete document before using a value in a design.
- These devices can operate from 2.3 V to 5.5 V with a typical current consumption of 120 μA per channel.
- The LMX3xx series also exhibits a 1.3 MHz gain bandwidth and they can drive capacitive loads.
- VCC-Vin must not exceed 6 V, Vin must not exceed 6 V.
- Human body model: 100 pF discharged through a 1.5 k Ω resistor between two pins of the device, done for all couples of pin combinations with other pins floating.
- Machine model: a 200 pF cap is charged to the spec ified voltage, then discharged directly between two combinations with other pins floating.
- Electrical characteristics at VCC+ = 2.7 V with VCC- = 0 V, Vicm = VCC/2, Tamb = 25° C, and Table 5.
- Electrical characteristics at VCC+ = 5 V with VCC- = 0 V, Vicm = VCC/2, Tamb = 25° C, and See Section 4.4: Input offset voltage drift over temperature. Figure 20.

Engineering review checklist
- Verify supply range, input common-mode range and output swing at the required load.
- Check offset, bias current, noise, bandwidth, slew rate and stability for the intended feedback network.
- Review supply decoupling, source impedance, capacitive-load behavior and thermal limits in the final layout.
Always confirm values against the latest manufacturer-controlled datasheet, especially when qualifying a substitute or releasing a production BOM.
