HJ412 is a high-speed JFET input operational amplifier with very low input offset voltage and guaranteed input offset voltage temperature drift coefficient. It requires only low supply current to achieve large gain bandwidth product and high conversion rate. In addition, the good matching characteristics of high-voltage JFET inputs provide very low input bias current and input offset current. The HJ412 pin is compatible with LF412 and CA3240. HJ412 is widely used in high-speed integrators, high-speed D/A converters, sample-and-hold circuits, and other electronic systems that require low input offset voltage, low drift, low input bias current, high input impedance, high conversion rate, and wide bandwidth.
Its main features are:
Input offset voltage is low at 1mV
Input offset voltage drift is 10µV/℃
Input bias current is low at 50pA
Input noise current is low at 0.01pA/
Gain bandwidth product is 3MHz
High conversion rate of 10 V/µs
Supply current is low at 1.8mA per amplifier
