The 1 pA input bias is the headline spec for high-impedance work. The 50 mA output current per channel can drive a headphone load or a small relay coil directly. The 2.4 mA total supply current for both channels keeps the power budget tight.
8-SOIC with 0.154-inch body width — standard footprint, easy to hand-solder or hot-air rework. No thermal pad underneath. Tube shipment means the parts arrive in a stiff plastic stick.
The TLC2272AID is the industrial-temperature-range (-40°C to 125°C) version of the TLC2272. The base TLC2272 typically has a narrower temperature grade; the 'A' suffix indicates the wider range. Functionally they are the same amplifier.
Standard dual op-amp pinout for an 8-SOIC: pin 1 = output A, pin 2 = inverting input A, pin 3 = non-inverting input A, pin 4 = V-, pin 5 = non-inverting input B, pin 6 = inverting input B, pin 7 = output B, pin 8 = V+.
The TLV9362IDDFR from TI is a newer dual CMOS rail-to-rail op-amp with 10.6 MHz GBW and 25 V/µs slew rate — a faster, lower-power alternative but not a pin-compatible drop-in due to different supply range and offset specs. For a direct functional equivalent, the TLC2272AID itself remains the primary choice.
