The AD741LH/+ is a general-purpose operational amplifier from Analog Devices in a TO-99-8 metal can package. Its 1 MHz -3 dB bandwidth and 0.5 V/µs slew rate define the small-signal and large-signal settling limits for loops like active filters, instrumentation amplifiers, and buffer stages where precision matters more than speed. The 10 V to 44 V supply span covers common industrial ±15 V rails and single-supply systems up to 36 V, so it drops into existing ±15 V BOMs without a rail change.
Supply range and input offset — fit for precision DC circuits
Minimum supply is 10 V, maximum 44 V, which means it runs cleanly on ±5 V (10 V total) through ±15 V or a single 36 V rail. Input offset voltage is 200 µV typical — tight enough for 12-bit DC accuracy with gain staging. Input bias current is 2 nA typical, so it won't load high-impedance sources like photodiode transimpedance stages the way a bipolar part with 100 nA bias would.
TO-99-8 metal can — package reality for the board
The AD741LH/+ comes in a TO-99-8 metal can, a through-hole hermetic package. That means a 0.1″ pin-circle footprint, no exposed pad, and a metal lid that shields the die from light and RF pickup.
However, the part is marked RoHS non-compliant — it contains lead in the solder dip or die-attach. That excludes it from EU RoHS-required assemblies unless a specific exemption applies. For non-RoHS or exempt military/industrial builds, it remains a current-production choice.
