Product details

JFET op-amp in an 8-DIP — what it brings to the board

The AD745JN is a single JFET-input operational amplifier from Analog Devices in an 8-pin DIP through-hole package. It delivers a 20 MHz gain-bandwidth product and a 12 V/µs slew rate, supplied from a single or dual rail spanning 9.6 V to 36 V total. Output can source or sink 40 mA. The 8 mA supply current is moderate for this speed grade.

No last-time-buy window, no NRND flag. For new designs or MRO replenishment on existing boards, the supply channel is stable.

The AD745JN is available to order through independent distribution.

Frequently asked questions

What is the exact replacement or equivalent for AD745JN?

There is no single direct replacement announced by Analog Devices. The AD712KNZ is a dual JFET op-amp with 4 MHz GBW and 20 V/µs slew rate in a through-hole package — a functional alternative if your circuit can accept two amplifiers and a different speed/slew profile. The AD711JRZ-REEL7 is a single-channel surface-mount option with 4 MHz / 20 V/µs. Neither is a pin-for-pin drop-in; verify the pinout and compensation before substituting.

What are the complete specifications and pinout of AD745JN?

Key specifications: JFET amplifier type, single circuit, 20 MHz gain-bandwidth product, 12 V/µs slew rate, 150 pA input bias current, 250 µV input offset voltage, 8 mA supply current, 40 mA output current per channel, supply range 9.6 V to 36 V, operating temperature 0°C to 70°C. Package: 8-DIP (0.300", 7.62 mm), supplier device package 8-PDIP. The standard 8-pin DIP pinout applies: offset null (1 and 5), inverting input (2), non-inverting input (3), V- (4), output (6), V+ (7), and NC (8).

Can AD745JN be replaced by a common op-amp like TL071 or LF356?

The TL071 and LF356 are both JFET-input op-amps in 8-DIP packages, making them footprint-compatible. However, the AD745JN offers a higher gain-bandwidth product (20 MHz vs 3-4 MHz typical for TL071/LF356) and a different slew rate. For a direct replacement in a circuit that relies on the AD745JN's 20 MHz bandwidth, the TL071 or LF356 will roll off earlier. For slower or DC-precision circuits, they may work after checking supply range and offset voltage.
