Parametric fit for signal-conditioning BOMs
The TLV2772CDR is a CMOS dual operational amplifier from Texas Instruments, offering a 5.1 MHz gain-bandwidth product and a 10.5 V/µs slew rate — the GBW sets the usable closed-loop bandwidth for signals up to several hundred kilohertz, while the slew rate ensures the output can track a full-swing 5 V step in under 500 ns without slew-induced distortion. Operating from a single 2.5 V to 5.5 V supply span, it fits 3.3 V and 5 V systems without a negative rail. The rail-to-rail output swings within millivolts of each supply rail, maximising dynamic range in low-voltage ADC driver or headphone amplifier stages. Each channel draws 1 mA supply current — for a dual-channel device that is 2 mA total quiescent, low enough for multi-channel data-acquisition boards or battery-powered instruments where every milliamp counts.
Package, temperature grade, and compliance
Housed in an 8-pin SOIC with a standard 3.90 mm body width and 1.27 mm lead pitch, the footprint matches the industry-wide SO-8 land pattern — no board spin required for a drop-in replacement in existing layouts. Rated for the commercial temperature range of 0°C to 70°C, this part is suited for indoor, controlled-environment equipment — office peripherals, instrumentation, and telecom line cards — but not for automotive under-hood or outdoor industrial enclosures where ambient exceeds 70°C. Texas Instruments lists the product status as Active and ROHS3 compliant — no last-time-buy risk, no RoHS exemption expiry to track. Suitable for both new designs and production replenishment.
Input-stage precision for sensor front-ends
The CMOS input stage draws only 2 pA of input bias current — at 25°C this is negligible for sensors with source impedance up to 10 MΩ, such as pH probes or photodiode amplifiers. The input offset voltage is 500 µV, which translates to a 0.5% error on a 100 mV full-scale signal — adequate for 8- to 10-bit accuracy chains without auto-zeroing. Each output can source or sink 50 mA — enough to drive a 16 Ω headphone load at 3.3 V or a 10-bit SAR ADC's sample-and-hold capacitor directly, though the rail-to-rail swing into a heavy load will clip before reaching the supply rails by about 200 mV at 50 mA.
Sourcing and availability
Quoted to order against the BOM quantity through independent distribution; availability and current pricing confirmed at RFQ time. Available in Tape & Reel (TR) or Cut Tape (CT) packaging options — the reel format suits automated pick-and-place assembly, while cut tape works for prototype or low-volume builds.
