Product details
Overview
TLC2262QDRG4 from Texas Instruments is a dual rail-to-rail output operational amplifier in an 8-pin SOIC package, designed for automotive-grade signal conditioning. It delivers 12 nV/√Hz input voltage noise at 1 kHz, 1 pA typical input bias current, and 500 µA maximum supply current per amplifier, enabling precision low-power sensing in single- or split-supply systems up to ±8 V.
For engineers reviewing the TLC2262QDRG4 datasheet, TLC2262QDRG4 pinout, TLC2262QDRG4 application, or TLC2262QDRG4 equivalent, key selection criteria include its rail-to-rail output swing (enabling full dynamic range with ADCs), low-noise performance for high-impedance sources like piezoelectric transducers, and Q-temp automotive qualification (–40°C to 125°C).
Technical Context
The TLC2262QDRG4 uses Advanced LinCMOS™ process technology to achieve rail-to-rail output swing while maintaining low input bias current (1 pA typ) and low noise (12 nV/√Hz at 1 kHz). Its common-mode input voltage range extends to the negative rail, supporting true single-supply operation down to 4.4 V total supply.
It features a gain-bandwidth product of 0.71 MHz and slew rate of 0.55 V/µs (typ) under 5 V supply, optimized for medium-speed precision applications where micropower efficiency and ac performance are balanced-distinct from both the ultra-low-power TLC225x and higher-speed TLC227x families.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±2.2 V to ±8 V - supports wide-range single- or split-supply operation including 5 V and ±5 V systems |
| Input Bias Current | 1 pA typ - enables accurate amplification of signals from high-impedance sources (e.g., piezo sensors) |
| Input Voltage Noise | 12 nV/√Hz at 1 kHz - 3× lower than prior-generation CMOS op-amps, critical for low-level signal integrity |
| Output Swing | Rail-to-rail - delivers full-scale output (e.g., 0.01 V to 4.99 V on 5 V supply), maximizing ADC utilization |
| Quiescent Current | 500 µA max per amplifier - enables battery-powered monitoring with multi-year runtime |
| Input Offset Voltage | 2.5 mV max (full temp range) - specified for industrial and automotive operation without trimming |
| Operating Temperature | –40°C to 125°C - qualified per automotive standards (Q-temp), suitable for under-hood and ADAS subsystems |

| 3 | IN+ A | Non-inverting input of Amplifier A - same high-impedance, common-mode range includes negative rail |
| 4 | VDD– / GND | Negative supply or ground reference - dual-supply (VDD–) or single-supply (GND) configuration |
| 5 | VDD+ | Positive supply - accepts up to +8 V (or ±8 V in split mode); powers both amplifiers |
| 6 | IN– B | Inverting input of Amplifier B - electrically isolated, identical specs to IN– A |

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 |
|---|---|---|---|
| TLV2432IDR | Higher slew rate (1.5 V/µs), wider GBW (2.5 MHz), but higher supply current (650 µA max) and no automotive qualification | Better for higher-frequency control loops (e.g., motor phase current sensing), not suitable for AEC-Q100 designs | Select TLV2432IDR only if bandwidth >1 MHz is required and automotive qualification is unnecessary |
| TLC2272QDRG4 | Improved ac performance (1.7 MHz GBW, 1.3 V/µs slew), same Q-temp rating, but higher noise (19 nV/√Hz) and input bias current (10 pA) | Preferred for active filters and audio preamps where speed outweighs noise sensitivity | Choose TLC2272QDRG4 when system bandwidth exceeds 500 kHz and 12 nV/√Hz noise is not critical |
Compared with TLV2432IDR and TLC2272QDRG4, the TLC2262QDRG4 uniquely balances ultra-low input bias current, low noise, and automotive qualification-making it optimal for precision, low-power, high-reliability sensor interfaces where speed is secondary to signal integrity and environmental robustness.

FAQ
What is the maximum supply voltage for the TLC2262QDRG4?
The TLC2262QDRG4 supports a total supply voltage range of ±2.2 V to ±8 V, meaning it operates with split supplies up to ±8 V or single supplies up to 16 V. Absolute maximum ratings specify VDD+ ≤ +8 V and VDD– ≥ –8 V. Exceeding these limits risks permanent damage, and recommended operation stays within ±8 V for reliable performance across –40°C to 125°C.
Does the TLC2262QDRG4 support true single-supply operation with input signals near ground?
Yes, the TLC2262QDRG4 supports true single-supply operation: its common-mode input voltage range includes the negative rail (VDD– or GND), and the input stage functions down to VDD– – 0.3 V. When powered from 0 V and +5 V, inputs can be taken from 0 V up to +3.5 V (full range), enabling direct interfacing with ground-referenced sensors without level-shifting circuitry.
Is the TLC2262QDRG4 pin-compatible with the standard TLC2262CDR or TLC2262IDR?
Yes, the TLC2262QDRG4 shares identical 8-pin SOIC (D) package dimensions and pinout with TLC2262CDR and TLC2262IDR. All three use the same top-view pin mapping: OUT A, IN– A, IN+ A, VDD–/GND, VDD+, IN– B, IN+ B, OUT B. However, the Q-suffix denotes automotive qualification (–40°C to 125°C, enhanced reliability testing), while C/I variants are commercial/industrial grade.
What is the typical input offset voltage drift over temperature for the TLC2262QDRG4?
The TLC2262QDRG4 has a temperature coefficient of input offset voltage (αVIO) of 2 µV/°C, measured from 25°C to 70°C. Over its full operating range (–40°C to 125°C), the maximum input offset voltage is specified as 2.5 mV - this includes initial offset plus drift. Long-term drift is 0.003 µV/month (25°C, extrapolated), indicating exceptional stability in deployed automotive and industrial systems.
Can the TLC2262QDRG4 drive capacitive loads directly, such as ADC input capacitors?
The TLC2262QDRG4 is stable with capacitive loads up to 100 pF when using a 50 kΩ load resistor, as confirmed by phase margin (56°) and gain margin (11 dB) measurements in the datasheet. For larger capacitive loads (e.g., >100 pF), external isolation resistance (≥100 Ω) is recommended to maintain stability. Its closed-loop output impedance is 240 Ω at 100 kHz, facilitating robust driving of typical SAR ADC sample capacitors.
