Dual op-amp with 320 mA output drive
The TLV4112IDGN is a dual-channel general-purpose op-amp from Texas Instruments, delivering a gain-bandwidth product of 2.7 MHz and a per-channel output current of 320 mA — enough to drive headphones, small relays, or the input stage of a downstream power amplifier without a separate buffer. Each channel draws 700 µA supply current (both channels active), keeping the total quiescent draw under 1.4 mA — relevant for battery-powered or multi-channel signal-conditioning boards where the op-amp budget shares a rail with the ADC or sensor bias.
Supply rails and analog performance
Rail-to-rail output swing lets the signal reach the supply rails, preserving dynamic range in low-voltage single-supply chains. Input bias current is 0.3 pA typical, so high-impedance sources (pH probes, photodiode front-ends) see negligible loading. Input offset voltage is 175 µV typical, which sets the DC accuracy floor for precision applications.
Package and thermal interface
Housed in an 8-HVSSOP with an exposed pad (the 8-TSSOP/MSOP footprint with 0.118-inch body width). Surface-mount only; the tube packaging means the parts ship in anti-static tubes, not tape-and-reel — factor this into pick-and-place feeder setup if the line is set up for reels.
An engine-bay sensor interface or an outdoor PLC analog input module that sees 105°C on a hot day still has margin before the die hits the upper limit.
