The LF247DT: Quad JFET-input op-amp with 20 pA input bias current, 4 MHz gain-bandwidth product, and 16 V/µs slew rate. Supply range spans to 44 V total. Each amplifier draws 1.4 mA supply current.
Supplied in a 14-SO (0.154" body width, 3.90 mm) package, surface-mount only. Operating range -40°C to 105°C.
Active lifecycle status with ROHS3 compliance. No last-time-buy or obsolescence notice in effect.
The LF247DT uses the standard quad op-amp pinout for a 14-SOIC package: output 1 (pin 1), inverting input 1 (pin 2), non-inverting input 1 (pin 3), V+ (pin 4), non-inverting input 2 (pin 5), inverting input 2 (pin 6), output 2 (pin 7), output 3 (pin 8), inverting input 3 (pin 9), non-inverting input 3 (pin 10), V- (pin 11), non-inverting input 4 (pin 12), inverting input 4 (pin 13), output 4 (pin 14).
The gain-bandwidth product is 4 MHz, which determines the closed-loop bandwidth for a given gain setting. For example, at a gain of 10 the usable bandwidth is approximately 400 kHz.
