Product details
Overview
TLV2442QDRG4Q1 from Texas Instruments is a dual, automotive-qualified rail-to-rail output operational amplifier with 1.8 MHz gain-bandwidth product, 750 µA per channel supply current, and 16 nV/√Hz input voltage noise at 1 kHz. It operates from 2.7 V to 10 V, delivers ±3 mA into 600 Ω loads, and supports common-mode input range from VDD– to (VDD+ – 1) V - enabling precision signal conditioning in battery-powered sensor interfaces and ADC driver stages.
For engineers reviewing the TLV2442QDRG4Q1 datasheet, TLV2442QDRG4Q1 pinout, TLV2442QDRG4Q1 application, or TLV2442QDRG4Q1 equivalent, key selection considerations include its AEC-Q100 Grade 1 qualification (–40°C to 125°C), 950 µV max input offset voltage (TLV2442A-Q1 variant), no phase inversion behavior, and 600-Ω output drive capability for telecom and automotive analog front-ends.
Technical Context
The TLV2442QDRG4Q1 uses Advanced LinCMOS™ process technology to achieve rail-to-rail output swing while maintaining low input bias current (1 pA typ) and extended common-mode input range (0 V to 4.25 V min at 5-V supply). Its architecture avoids phase inversion when inputs approach supply rails - a critical advantage over standard CMOS op-amps in high-gain sensor amplification.
It features internal compensation optimized for stable operation with 600 Ω loads and 100 pF capacitive loads, delivering 65° phase margin and 9 dB gain margin at unity gain. The device is fully characterized across –40°C to 125°C and specified for both 3-V and 5-V single-supply operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 10 V - supports wide-input automotive and industrial power rails without external regulation. |
| Gain-Bandwidth Product | 1.8 MHz (typ at 5 V) - enables stable closed-loop operation up to ~100 kHz with moderate gain (e.g., AV = 10). |
| Input Offset Voltage | 950 µV max (TLV2442A-Q1 variant) - ensures ≤0.5% error in 0.5 V full-scale 12-bit ADC driver applications. |
| Output Drive Capability | ±3 mA into 600 Ω (VOH ≥2.25 V, VOL ≤1 V at 5 V) - directly interfaces with legacy telecom line drivers and SAR ADC reference buffers. |
| Input Voltage Noise | 16 nV/√Hz at 1 kHz (5 V) - suitable for low-level piezoelectric transducer and thermopile signal amplification. |
| Common-Mode Input Range | 0 V to 4.25 V min (5 V supply) - allows direct sensing of ground-referenced signals without level-shifting circuitry. |
| Quiescent Current | 750 µA per channel (typ) - enables dual-channel operation in <2 mW total power budget systems (e.g., tire pressure sensors). |
Pinout & Package
TLV2442QDRG4Q1 is housed in an 8-pin SOIC (D package) with exposed pad thermal enhancement. Pin numbering follows standard IC orientation (pin 1 marked by dot or notch).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Inverting amplifier output - rail-to-rail swing (0 V to VDD) supports full-scale ADC input driving. |
| 2 | IN– A | Inverting input - high impedance (1 TΩ differential, 1 TΩ common-mode) minimizes loading on high-Z sources. |
| 3 | IN+ A | Non-inverting input - matched to IN– A for optimal CMRR; no phase inversion up to supply rails. |
| 4 | GND / VDD– | Power return - shared ground reference for dual amplifier; must be low-impedance for noise immunity. |
| 5 | IN+ B | Non-inverting input (Channel B) - electrically isolated from Channel A; enables independent sensor conditioning paths. |
| 6 | IN– B | Inverting input (Channel B) - identical specs to Channel A; supports differential pair or dual single-ended configurations. |
| 7 | OUT B | Output (Channel B) - independently buffered; allows simultaneous processing of two analog channels. |
| 8 | VDD+ | Positive supply - accepts 2.7–10 V; internal ESD protection >2 kV HBM ensures robustness in automotive harness environments. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail output swing | Drives within 10 mV of VDD and GND at light loads - maximizes dynamic range for 3.3 V or 5 V ADCs without level-shifting. |
| No phase inversion | Operates linearly with inputs driven to VDD or GND - eliminates latch-up risk in overvoltage transient conditions (e.g., load dump). |
| Automotive qualification | AEC-Q100 Grade 1 (–40°C to 125°C) - qualified for engine control, body electronics, and ADAS sensor signal chains. |
| Low input bias current | 1 pA typical - preserves accuracy in high-impedance pH, ion-selective, or photodiode transimpedance amplifier designs. |
| 600-Ω output drive | Sustains ±3 mA into 600 Ω at 5 V - meets telecom line-driver requirements and drives SAR ADC reference inputs directly. |
| Low-noise performance | 16 nV/√Hz at 1 kHz - enables resolution of sub-mV signals from strain gauges and RTDs without additional filtering. |

FAQ
What is the maximum operating temperature for TLV2442QDRG4Q1?
The TLV2442QDRG4Q1 is qualified for continuous operation from –40°C to +125°C ambient temperature per AEC-Q100 Grade 1 requirements. This rating is validated across all electrical parameters in the datasheet, including input offset voltage, CMRR, and output drive capability - making it suitable for under-hood and powertrain applications where thermal stress is extreme.
Does TLV2442QDRG4Q1 support true rail-to-rail input?
No, TLV2442QDRG4Q1 features rail-to-rail *output* only. Its common-mode input voltage range extends from VDD– to (VDD+ – 1) V - for example, 0 V to 4.25 V minimum at 5-V supply. While this exceeds standard CMOS op-amps, it does not include the negative rail. However, it exhibits no phase inversion when inputs reach either rail, a key functional advantage over many competitors.
Can TLV2442QDRG4Q1 drive a 100-pF capacitive load stably?
Yes, TLV2442QDRG4Q1 is internally compensated for stable operation with 100-pF capacitive loads and 600-Ω series resistance, achieving 65° phase margin and 9 dB gain margin at unity gain. This is explicitly verified in the datasheet's Operating Characteristics table and Figure 18–19 frequency response plots - confirming suitability for driving ADC input capacitors and long PCB traces.
What is the input offset voltage specification for TLV2442QDRG4Q1?
TLV2442QDRG4Q1 has a maximum input offset voltage of 2.5 mV over the full –40°C to +125°C temperature range. This value is distinct from the TLV2442A-Q1 variant (950 µV max), and is confirmed in the Ordering Information table and Electrical Characteristics section of the SGLS181C datasheet. It reflects the standard-grade version optimized for cost-sensitive automotive applications where ultra-high DC precision is not required.
Is TLV2442QDRG4Q1 pin-compatible with other devices in the TLV244x-Q1 family?
Yes, TLV2442QDRG4Q1 shares identical pinout and package (SOIC-8) with TLV2442AQPWRQ1, TLV2442QDGKRQ1, and TLV2442AQDRQ1. All dual variants use the same D, PW, or DGK footprints and terminal assignments - enabling drop-in replacement during design iteration or qualification testing, provided supply and layout constraints (e.g., thermal pad for PW/DGK) are observed.
