The versatile three op amp design and small size make these amplifiers an excellent choice for a wide range of applications. Currentfeedback input circuitry provides wide bandwidth even at high gain (200 k Hz at G = 100). A single external resistor sets any gain from 1 to 10,000. The INA128 provides an industry-standard gain equation with a 50-kΩ resistor. The INA129 gain equation uses a 49.4-kΩ resistor to allow for drop-in replacements of parable devices. The INA12x are available in plastic DIP and surfacemount packages, specified for the - 40°C to +85°C temperature range. The INA128 is also available in a dual configuration, the INA2128. The upgraded INA828 offers a lower input bias current (0.6 n A, max) and lower noise (7 n V/√Hz) at the same quiescent current. See the Device parison Table for a selection of precision instrumentation amplifiers from Texas Instruments.
