These amplifiers combine very low noise and supply current with a 100MHz gain bandwidth product, a 25V/µs slew rate, and are optimized for low supply signal conditioning systems. These amplifiers maintain their performance for supplies from 2.5V to 12.6V and are specified at 3V, 5V and ±5V supplies. Harmonic distortion is less than – 80dBc at 1MHz making these amplifiers suitable in low power data acquisition systems. These devices can be used as replacements for many op amps to improve input/output range and noise performance.

Exposure to any Absolute Maximum Rating condition for extended periods may affect device reliability and lifetime. Note 2: Inputs are protected by back-to-back diodes and diodes to each supply. If the inputs are taken beyond the supplies or the differential input voltage exceeds 0.7V, the input current must be limited to less than 40mA. Note 3: Junction temperatures must be kept below the absolute maximum rating when the output is shorted indefinitely. Note 4: Matching parameters are the difference between the two amplifiers of the LT6203X. CMRR and PSRR match are defined as follows: CMRR and PSRR are measured in µV/V on the identical amplifiers. The difference is calculated between the matching sides in µV/V. The result is converted to dB. 4 Note 5: Minimum supply voltage is guaranteed by power supply rejection ratio test. Note 6: Output voltage swings are measured between the output and power supply rails. Note 7: Full-power bandwidth is calculated from the slew rate: FPBW = SR/2πVP Note 8: Differential gain and phase are measured using a Tektronix TSG120YC/NTSC signal generator and a Tektronix 1780R Video Measurement Set. The resolution of this equipment is 0.1% and 0.1°. Ten identical amplifier stages were cascaded giving an effective resolution of 0.01% and 0.01°.
