Product details
Overview
TLV2442QDR from Texas Instruments is a dual, rail-to-rail output operational amplifier optimized for automotive-grade operation (–40°C to 125°C), featuring 950 µV max input offset voltage at 25°C, 1.8 MHz gain-bandwidth product, and 750 µA per channel supply current at 5 V. It delivers 600-Ω load drive capability and operates from 2.7 V to 10 V supplies, making it suitable for precision signal conditioning in automotive sensor interfaces and low-voltage data acquisition systems.
For engineers reviewing the TLV2442QDR datasheet, TLV2442QDR pinout, TLV2442QDR application, or TLV2442QDR equivalent, key selection criteria include its extended common-mode input range (0 V to 4.25 V min at 5 V), no phase inversion behavior near supply rails, low 16 nV/√Hz input noise at 1 kHz, and Q-temp qualification for high-reliability automotive use.
Technical Context
The TLV2442QDR uses Advanced LinCMOS™ process technology to achieve rail-to-rail output swing while maintaining wide-input-voltage operation and eliminating phase inversion at supply rail extremes. Its input stage supports common-mode voltages down to VDD– and up to VDD+ – 1.3 V across the full temperature range.
It integrates a high-gain, low-noise transconductance stage with robust output buffering capable of sourcing/sinking ±5 mA while sustaining <1.3 V/mV large-signal voltage amplification into 600-Ω loads at 5 V supply - enabling direct interfacing with ADCs and low-impedance transducers without external gain stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 10 V - supports single-supply battery-powered and automotive 5 V/12 V systems with headroom margin. |
| Input Offset Voltage (max) | 950 µV at TA = 25°C - enables accurate DC-coupled amplification in precision sensor front-ends. |
| Gain-Bandwidth Product | 1.8 MHz typ at VDD = 5 V - sufficient for anti-aliasing filtering and moderate-speed signal conditioning up to ~100 kHz closed-loop bandwidth. |
| Output Drive Capability | 600-Ω load drive - allows direct connection to telecom line drivers, ADC reference buffers, and analog multiplexers without external buffers. |
| Input Bias Current | 1 pA typ - preserves signal integrity when amplifying high-impedance sources like piezoelectric sensors or pH electrodes. |
| Rail-to-Rail Output Swing | Swings within 100 mV of both rails at 5 V - maximizes dynamic range in single-supply systems interfacing with 12-bit+ ADCs. |
| Common-Mode Input Range | 0 V to 4.25 V min at 5 V supply - accommodates ground-referenced inputs and high-side sensing without level-shifting. |
Pinout & Package
TLV2442QDR is housed in an 8-pin TSSOP (PW) package with exposed thermal pad, qualified for automotive temperature range (–40°C to 125°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT1) | Amplifier 1 output | Delivers rail-to-rail output voltage; capable of driving 600-Ω loads with <100 mV saturation near rails. |
| 2 (IN–1) | Inverting input, Amp 1 | High-impedance node (1000 GΩ); accepts signals within 0 V to 4.25 V at 5 V supply without phase inversion. |
| 3 (IN+1) | Non-inverting input, Amp 1 | Same high-Z and common-mode range as IN–1; used for unity-gain buffers or non-inverting configurations. |
| 4 (GND / VDD–) | Negative supply / ground reference | Serves as return path for both amplifiers; must be low-impedance to maintain CMRR >70 dB. |
| 5 (IN+2) | Non-inverting input, Amp 2 | Independent input for second amplifier; identical specs and layout symmetry to IN+1. |
| 6 (IN–2) | Inverting input, Amp 2 | Matches IN–1 performance; supports dual-channel differential sensing or independent signal paths. |
| 7 (OUT2) | Amplifier 2 output | Functionally identical to OUT1; enables dual-channel signal conditioning on single die. |
| 8 (VDD+) | Positive supply | Accepts 2.7–10 V; internal regulation ensures stable biasing across automotive voltage transients. |
Key Features
| Feature | Design Value |
|---|---|
| No phase inversion | Eliminates output glitches when common-mode input approaches VDD or GND - critical for sensor monitoring during power-up/down or fault conditions. |
| Rail-to-rail output | Enables full utilization of ADC input range in 3 V or 5 V systems, increasing effective resolution by up to 1 LSB in 12-bit conversions. |
| Low input bias current (1 pA) | Minimizes voltage error across high-value feedback networks (>1 MΩ), preserving gain accuracy in precision integrators and charge amplifiers. |
| Automotive Q-temp qualification | Meets AEC-Q100 stress testing requirements for temperature cycling, HAST, and ESD - validated for under-hood and infotainment applications. |
| Extended common-mode input range | Supports direct connection to 0–5 V industrial sensors and automotive transducers without external level-shifting circuitry. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual rail-to-rail output op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV722QDR | Lower GBW (1.5 MHz), higher input offset (1.25 mV max), same Q-temp grade and TSSOP-8 package. | Less suitable for high-frequency sensor excitation or fast-settling data acquisition due to reduced bandwidth and accuracy. | Choose LMV722QDR only if cost sensitivity outweighs need for 1.8 MHz GBW and 950 µV VIO. |
| TSV912IQDR | Higher GBW (8 MHz), lower noise (12 nV/√Hz), but only rated to 85°C ambient (not automotive 125°C). | Not qualified for under-hood or battery-pack mounting; requires derating or additional thermal management in high-temp environments. | Select TSV912IQDR only for non-automotive industrial applications where extended temperature range is not required. |
Compared with LMV722QDR and TSV912IQDR, TLV2442QDR uniquely balances automotive temperature qualification, 950 µV precision, 1.8 MHz bandwidth, and 600-Ω drive strength - making it optimal for space-constrained, high-reliability dual-channel analog front-ends where thermal robustness and DC accuracy are co-prioritized.

FAQ
What is the operating temperature range for TLV2442QDR?
The TLV2442QDR is qualified for operation from –40°C to +125°C ambient temperature, meeting AEC-Q100 Grade 1 requirements for automotive applications. This rating is confirmed in the "Operating free-air temperature range" section of the SLOS169H datasheet, where the Q suffix explicitly denotes the –40°C to 125°C range.
Does TLV2442QDR support rail-to-rail input operation?
No, TLV2442QDR features rail-to-rail *output* swing but not rail-to-rail input. Its common-mode input voltage range extends from VDD– to VDD+ – 1.3 V at full temperature range, meaning it accepts inputs down to ground but not fully up to the positive rail. This is documented in the "Recommended Operating Conditions" table for Q-suffix devices.
What is the maximum load drive capability of TLV2442QDR?
TLV2442QDR can drive 600-Ω loads while maintaining rail-to-rail output swing - verified in the "Electrical Characteristics" tables at both 3 V and 5 V supplies. At 5 V, VOH ≥ 4 V and VOL ≤ 1.25 V with 5 mA output current, confirming robust low-impedance drive for ADC interfaces and analog multiplexers.
Is TLV2442QDR pin-compatible with other members of the TLV244x family?
Yes, TLV2442QDR shares identical pinout and footprint with all TLV2442 variants in the TSSOP-8 (PW) package, including TLV2442CDR, TLV2442AIPW, and TLV2442QPW. The pin configuration is standardized across the dual-amplifier variants and shown explicitly in the "TLV2442 PW PACKAGE (TOP VIEW)" diagram in the datasheet.
What packaging options are available for TLV2442QDR?
TLV2442QDR is supplied exclusively in the 8-pin TSSOP (PW) package with thermal pad, tape-and-reel format (indicated by the 'R' suffix). The datasheet's "TLV2442 AVAILABLE OPTIONS" table confirms that only the D (SOIC-8) and PW (TSSOP-8) packages are offered for Q-suffix variants, and TLV2442QDR corresponds to the TSSOP variant.
