Frequently Asked Questions
What is the gain range of the INA118UB and how is it set?
The INA118UB supports a gain range from 1 to 10,000. The gain is set using a single external resistor connected between pins 1 and 8 (RG). The gain formula is G = 1 + (50kΩ / RG), allowing precise and flexible gain configuration without complex external circuitry.
What supply voltage does the INA118UB require?
The INA118UB operates over a wide supply voltage range of ±1.35V to ±18V, making it compatible with both single-supply and dual-supply systems. This flexibility allows it to be used in battery-powered portable devices as well as standard ±15V industrial instrumentation systems.
What are the typical applications for the INA118UB?
The INA118UB is commonly used in medical instruments (ECG, patient monitoring), industrial data acquisition, bridge sensor signal conditioning with strain gauges and pressure transducers, thermocouple amplification, and precision portable measurement equipment where low noise (8nV/√Hz) and low offset voltage (0.05mV max) are essential.
What package does the INA118UB come in?
The INA118UB is housed in an 8-pin SOIC (Small Outline Integrated Circuit) surface-mount package, which provides a compact footprint suitable for space-constrained PCB designs while offering good thermal performance and ease of automated assembly.
