Product details
Overview
TLC2262CDR from Texas Instruments is a dual rail-to-rail output operational amplifier in SOIC-8 package, delivering 12 nV/√Hz input noise at 1 kHz, 500 µA max supply current, and ±2.2 V to ±8 V dual-supply operation. It supports precision signal conditioning in battery-powered sensor interfaces and single-supply ADC driver applications.
For engineers reviewing the TLC2262CDR datasheet, TLC2262CDR pinout, TLC2262CDR application, or TLC2262CDR equivalent, this page provides verified electrical specifications, validated D-package pin mapping, real-world use cases for low-noise analog front-ends, and two confirmed alternative op-amps with documented performance trade-offs.
Technical Context
The TLC2262CDR uses Advanced LinCMOS™ process technology to achieve rail-to-rail output swing while maintaining CMOS-level input bias current (1 pA typ) and low noise. Its input stage includes negative rail–referenced common-mode range and fully specified operation across 0°C to 70°C ambient temperature.
It features a unity-gain stable architecture with 0.55 V/µs slew rate (typ), 0.71 MHz gain-bandwidth product, and 56° phase margin-enabling stable closed-loop configurations driving capacitive loads up to 100 pF without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±2.2 V to ±8 V - supports both split-supply industrial systems and single-supply 5 V microcontroller interfaces |
| Input Offset Voltage | 2500 µV max at 25°C - enables DC-coupled amplification of mV-level transducer signals without trimming |
| Input Bias Current | 1 pA typ - preserves high-impedance source integrity (e.g., piezoelectric sensors, pH electrodes) |
| Output Swing | Rail-to-rail - delivers full dynamic range into ADCs with 0–5 V input spans, minimizing headroom loss |
| Equivalent Input Noise | 12 nV/√Hz at 1 kHz - 3× lower than predecessor TLC27M2, critical for low-amplitude audio/sensor signal chains |
| Supply Current per Amplifier | 500 µA max - allows dual-channel operation in sub-1 mA total system power budgets |
| Common-Mode Input Range | Includes negative rail - permits direct sensing of ground-referenced signals without level-shifting circuitry |
Pinout & Package
Package: SOIC-8 (D package), tape-and-reel format (R suffix). RoHS-compliant, surface-mountable, 1.27 mm pitch.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Amplifier 1 output - drives loads up to ±50 mA, rail-to-rail swing under 50 kΩ load |
| 2 | IN1– | Inverting input of Amp1 - high-impedance node (10¹² Ω), sensitive to PCB leakage paths |
| 3 | IN1+ | Non-inverting input of Amp1 - accepts common-mode voltages down to VDD– (ground in single-supply) |
| 4 | VDD– / GND | Negative supply or ground reference - must be low-impedance; shared return for both amplifiers |
| 5 | IN2+ | Non-inverting input of Amp2 - electrically isolated from Amp1 inputs; same CMVR as Pin 3 |
| 6 | IN2– | Inverting input of Amp2 - matched bias current to Pin 2, enabling precision differential configurations |
| 7 | OUT2 | Amplifier 2 output - independent output stage; no internal cross-coupling with OUT1 |
| 8 | VDD+ | Positive supply - decoupling capacitor (0.1 µF ceramic) required within 5 mm for stability |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output | Swings within 10 mV of VDD+ and VDD– at 100 µA load - eliminates need for level-shifting before 12-bit+ SAR ADCs |
| Low input bias current | 1 pA typical - enables >100 MΩ sensor interface impedance without significant DC error |
| Low noise density | 12 nV/√Hz at 1 kHz - reduces integrated noise floor in 10 Hz–10 kHz bandwidths by 40% vs. TLC27M2 |
| Single- and split-supply support | Fully characterized at 5 V and ±5 V - simplifies design reuse across portable (3.3 V) and industrial (±15 V) platforms |
| High CMRR | 83 dB min at 25°C - rejects power supply ripple and EMI coupling in noisy environments |
Applications
| Portable Gas Sensor Interface | Industrial 4–20 mA Loop Receiver |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC2272CDR | Higher slew rate (2.1 V/µs), higher supply current (1.3 mA), 25 nV/√Hz noise | Better for wideband active filters (>100 kHz), less suitable for ultra-low-power designs | Select when bandwidth >1 MHz is required and power budget allows ≥2.6 mA total |
| TLV2432IDR | Wider input voltage range (rail-to-rail input), 600 µA supply current, 28 nV/√Hz noise | Enables true rail-to-rail input/output in single-supply systems where input may exceed VDD/2 | Choose when sensing signals near supply rails (e.g., battery voltage monitoring) is required |
Compared with TLC2262CDR, TLC2272CDR trades 2.6× higher power for 3.8× faster settling and wider GBW, while TLV2432IDR adds rail-to-rail input capability at the cost of 2.3× higher noise-making TLC2262CDR optimal for low-noise, low-power dual-opamp roles where input common-mode stays within VDD– to VDD+–1.5 V.

FAQ
What is the maximum operating temperature range for the TLC2262CDR?
The TLC2262CDR is rated for 0°C to 70°C ambient operating temperature (C-suffix grade). This range is validated per the datasheet's recommended operating conditions and absolute maximum ratings tables, with full electrical characterization performed across this interval. The device is not qualified for industrial (–40°C to 125°C) or automotive temperature grades - those require TLC2262I or TLC2262Q variants.
Does the TLC2262CDR support true rail-to-rail input operation?
No, the TLC2262CDR does not support rail-to-rail input. Its common-mode input voltage range extends to the negative rail (VDD–) but only to VDD+ – 1.5 V under typical conditions. For example, at ±5 V supply, the input range is –5 V to +3.5 V. True rail-to-rail input capability requires alternatives like TLV2432IDR or TLV2211 series.
Can the TLC2262CDR drive a 100 pF capacitive load stably?
Yes, the TLC2262CDR maintains 56° phase margin with 100 pF capacitive load and 50 kΩ feedback resistance, as confirmed in the datasheet's operating characteristics tables. No external compensation is required for unity-gain stable configurations driving such loads, making it suitable for driving ADC input capacitors or long PCB traces.
What is the typical input offset voltage drift over temperature for TLC2262CDR?
The TLC2262CDR has a temperature coefficient of input offset voltage (αVIO) of 2 µV/°C, measured from 25°C to 70°C. Over its full 0°C to 70°C operating range, this results in ≤140 µV of additional offset shift beyond the 2500 µV maximum at room temperature - a predictable, linear contribution used in calibration routines.
Is the TLC2262CDR pin-compatible with the older TLC27M2CP?
No, the TLC2262CDR is not pin-compatible with TLC27M2CP. While both are dual op-amps in 8-pin D packages, TLC27M2CP uses a different pinout: Pin 1 = OUT1, Pin 2 = IN1–, Pin 3 = IN1+, Pin 4 = V–, Pin 5 = IN2+, Pin 6 = IN2–, Pin 7 = OUT2, Pin 8 = V+. TLC2262CDR follows the same sequence, but its improved specs (lower noise, rail-to-rail output) require layout verification - especially for bypassing and grounding - even if physical placement matches.
