TLC272 Dual Op-Amp

@@ -0,0 +1,54 @@+# TLC272++**Texas Instruments** · Operational Amplifier · SOIC-8++The TLC272 is a dual operational amplifier built on TI's LinCMOS process, giving high input impedance, low input bias current, and low power draw. It works from a single 3 V to 16 V supply and suits high-impedance sensor buffering, active filters, and general single-supply signal conditioning.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | 1OUT | output | Output of amplifier 1. Drives up to ±30 mA; high-level output typ 4.95 V at VDD = 5 V, RL = 10 kΩ; low-level output includes negative rail (0 V). |+| 2 | 1IN- | input | Inverting input of amplifier 1. High input impedance (>10^12 Ω typ), input bias current typ 10 pA at 25°C. Common-mode input voltage range extends to −0.1 V (below negative rail). |+| 3 | 1IN+ | input | Non-inverting input of amplifier 1. High input impedance (>10^12 Ω typ), input bias current typ 10 pA at 25°C. Common-mode input voltage range extends to −0.1 V (below negative rail). |+| 4 | GND | power_in | Negative supply / ground reference. Total current out of GND ≤ 45 mA (absolute max). Serves as the negative rail for single-supply operation. |+| 5 | 2IN+ | input | Non-inverting input of amplifier 2. High input impedance (>10^12 Ω typ), input bias current typ 10 pA at 25°C. Common-mode input voltage range extends to −0.1 V (below negative rail). |+| 6 | 2IN- | input | Inverting input of amplifier 2. High input impedance (>10^12 Ω typ), input bias current typ 10 pA at 25°C. Common-mode input voltage range extends to −0.1 V (below negative rail). |+| 7 | 2OUT | output | Output of amplifier 2. Drives up to ±30 mA; high-level output typ 4.95 V at VDD = 5 V, RL = 10 kΩ; low-level output includes negative rail (0 V). |+| 8 | VDD | power_in | Positive supply pin. Operating range 3 V to 16 V (C-suffix) or 4 V to 16 V (I-suffix); absolute max 18 V. Supply current typ 1.12 mA (both amplifiers, no load) at VDD = 5 V. |++## Key specifications++| Parameter | Value |+|---|---|+| Type | Dual CMOS op-amp |+| Supply voltage | 3 V to 16 V single, or +-1.5 V to +-8 V |+| Input impedance | 10^12 ohm typ |+| Input offset voltage | 1.1 mV typ |+| Slew rate | 4.5 V/us typ |+| Gain-bandwidth product | 1.7 MHz typ |+| Operating temperature | 0 C to 70 C |++## Ordering variants++- `TLC272P`+- `TLC272D`+- `TLC272PS`+- `TLC272PW`+- `TLC272JG`++## CAD (KiCad official)++- Symbol: `tlc272.kicad_sym`+- Footprint: `tlc272.kicad_mod`+- 3D model: SOIC-8 body from KiCad `Package_SO/SOIC-8_3.9x4.9mm_P1.27mm`.++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Texas Instruments datasheet](https://www.ti.com/lit/ds/symlink/tlc272.pdf) (36 pp, sha256 `00b6d1d3e858d223`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
