INA848ID General Description
The INA848 is a fixed-gain instrumentation amplifier optimized for high-precision measurements, such as very-small, fast, differential input signals. TIs super-beta topology provides a very low input bias current and current noise. The well-matched transistors help achieve a very low offset and offset drift. Matching of the internal resistors yields a high common-mode rejection ratio of 132 dB across the full input-voltage range, and a very low gain drift error of 5 ppm/⁰C (max).
The current-feedback topology of the INA848 produces a wide bandwidth of 2.8 MHz at a fixed gain of 2000, thereby eliminating the need for subsequent gain stages. The very-low noise floor of 1.3 nV/√Hz minimizes the impact on the equivalent number of bits (ENOB) when interfacing with high-resolution analog-to-digital converters (ADCs). The INA848 provides the flexibility of adding filters between the gain stages (pins 2 and 3) to maintain an adequate signal integrity.
These unique features of the INA848 make this device an excellent choice for applications requiring high-precision measurements, such as high-end medical instrumentation, electroencephalography, vibration sensing, and displacement measurements.
This device is designed for 8-V to 36-V single supplies, or ±4-V to ±18-V on dual supplies.
