The TL07xx, TL071 JFET-input operational amplifier family is designed to offer a wider previously developed operational amplifier. Each of these JFET-input operational amplifiers incorporates well-matched, high-voltage JFET and bipolar transistors in a monolithic integrated circuit.
A JFET-input operational amplifier, also known as a JFET op-amp, is an operational amplifier that incorporates a junction field-effect transistor (JFET) at its input stage. The JFET provides certain characteristics and benefits in terms of input impedance, input bias current, and noise performance compared to other types of op-amps.
1. Low Power Consumption
2. Wide Common-Mode and Differential Voltage Ranges
3. Low Input Bias and Offset Currents
4. Output Short-Circuit Protection
5. Low Total Harmonic Distortion: 0.003% Typical
JFET-input operational amplifiers are commonly used in a variety of applications where high input impedance, low input bias current, and low noise performance are critical. Examples include sensor interfaces, medical instrumentation, audio amplifiers, and precision measurement systems.
The OPA363 and OPA364 families are highperformance, CMOS operational amplifiers optimized for very low voltage, single-supply operation. These miniature, low-cost amplifiers are designed to operate on single supplies from 1.8 V (±0.9 V) to 5.5 V (±2.75 V). Applications include sensor amplification and signal conditioning in battery-powered systems. The OPA363 and OPA364 families offer excellent CMRR without the crossover associated with traditional complimentary input stages. This feature results in excellent performance for driving analog-todigital (A/D) converters without degradation of differential linearity and THD. The input commonmode range includes both the negative and positive supplies. The output voltage swing is within 10 mV of the rails. The OPA363 family includes a shutdown mode. Under logic control, the amplifiers can be switched from normal operation to a standby current that is less than 1 μA.
