Product details
Overview
TLV2252QDRG4 from Texas Instruments is a dual rail-to-rail output operational amplifier optimized for low-voltage, micropower applications. It delivers 34 µA per channel supply current, 19 nV/√Hz input voltage noise at 1 kHz, 850 µV max input offset voltage (TA = 25°C), and rail-to-rail output swing from 2.7 V to 8 V supply - enabling precision signal conditioning in battery-powered sensor interfaces and ADC front-ends.
For engineers reviewing the TLV2252QDRG4 datasheet, TLV2252QDRG4 pinout, TLV2252QDRG4 application, or TLV2252QDRG4 equivalent, key selection considerations include its automotive-grade −40°C to 125°C operating range, 1 pA typical input bias current, common-mode input range extending to the negative rail, and compatibility with single-supply 3 V systems requiring low-noise, low-power amplification.
Technical Context
The TLV2252QDRG4 uses Advanced LinCMOS™ process technology to achieve high input impedance (>10¹² Ω) and ultra-low input bias current (1 pA typ). Its rail-to-rail output stage supports full dynamic range utilization when driving successive stages like SAR ADCs or low-voltage comparators.
It operates fully specified across 2.7 V–8 V supplies and features a common-mode input voltage range that includes the negative rail - critical for ground-referenced sensor signals. The device exhibits 63° phase margin and 15 dB gain margin at unity gain with 50 kΩ load and 100 pF capacitive load, ensuring stable operation in high-impedance feedback networks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 8 V - supports direct integration into 3 V and 5 V battery-powered systems without level-shifting. |
| Supply Current per Channel | 34 µA typ - enables multi-year operation on coin-cell batteries in remote sensing nodes. |
| Input Offset Voltage | 850 µV max at TA = 25°C - ensures <1 LSB error when driving 12-bit ADCs with 3 V reference. |
| Input Voltage Noise | 19 nV/√Hz at f = 1 kHz - 4× lower than prior micropower CMOS op-amps, critical for piezoelectric transducer signal integrity. |
| Common-Mode Input Range | Includes negative rail (VDD−) - allows direct amplification of 0 V–VDD sensor outputs without biasing circuitry. |
| Output Swing | Rail-to-rail - delivers full-scale analog signal to ADC inputs, maximizing SNR and effective resolution. |
| Gain-Bandwidth Product | 0.187 MHz at VDD = 3 V - sufficient for anti-aliasing filters and DC-coupled sensor buffering up to ~100 kHz. |
Pinout & Package
TLV2252QDRG4 is housed in an 8-pin SOIC (D) package with standard pinout for dual op-amps. The package is RoHS-compliant, surface-mountable, and qualified for automotive temperature range (−40°C to 125°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Amplifier A) | High-impedance node accepting differential signal; requires matched trace routing to minimize offset drift. |
| 2 | Non-Inverting Input (Amplifier A) | Accepts reference or sensor signal; common-mode range extends to VDD−, enabling ground-sensed inputs. |
| 3 | Output (Amplifier A) | Rail-to-rail capable output; drives loads ≥10 kΩ directly or buffers ADC inputs with minimal headroom loss. |
| 4 | Ground / Negative Supply (VDD−) | Reference for both amplifiers; must be low-impedance return path to avoid PSRR degradation. |
| 5 | Positive Supply (VDD+) | Single or split supply connection; decoupling capacitor (0.1 µF) required within 5 mm for stability. |
| 6 | Output (Amplifier B) | Independent output stage; identical specs to Pin 3 - supports dual-channel signal paths without crosstalk. |
| 7 | Inverting Input (Amplifier B) | Matches Pin 1 functionality; layout symmetry recommended for matched gain configurations. |
| 8 | Non-Inverting Input (Amplifier B) | Matches Pin 2 functionality; usable for differential pair or independent sensor channel amplification. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-voltage operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2252IDR | Same silicon, industrial temp range (−40°C to 125°C) but non-automotive qualified; no AEC-Q100 documentation. | Not approved for automotive safety-critical or under-hood use; acceptable for commercial industrial equipment. | Select TLV2252IDR only if AEC-Q100 compliance is not required and cost sensitivity outweighs qualification assurance. |
| OPA2333AIDR | Zero-drift architecture; 0.02 µV/°C offset drift vs. TLV2252QDRG4's 0.5 µV/°C; higher 17 µA/channel current. | Better long-term DC stability in precision weigh scales; less suitable for ultra-low-power battery lifetime targets. | Choose OPA2333AIDR when offset drift dominates system error budget over quiescent power constraints. |
Compared with TLV2252IDR, TLV2252QDRG4 adds automotive qualification and configuration control; versus OPA2333AIDR, it trades zero-drift performance for 2× lower supply current and simpler design-in - making it optimal for cost-sensitive, battery-constrained automotive and industrial sensing where moderate DC accuracy suffices.

FAQ
What is the maximum operating temperature range for TLV2252QDRG4?
The TLV2252QDRG4 is qualified for continuous operation from −40°C to 125°C, meeting AEC-Q100 Grade 2 requirements for automotive applications. This rating is verified across all electrical parameters in the datasheet under recommended operating conditions, including supply voltages from 2.7 V to 8 V and full common-mode input range coverage.
Does TLV2252QDRG4 support single-supply operation?
Yes, TLV2252QDRG4 is fully specified for single-supply operation from 2.7 V to 8 V. Its common-mode input voltage range includes the negative rail (VDD−), and its rail-to-rail output swing allows full dynamic range utilization - making it ideal for 3 V microcontroller-based systems without dual supplies.
What is the input offset voltage specification for TLV2252QDRG4?
The TLV2252QDRG4 has a maximum input offset voltage of 850 µV at TA = 25°C (for the 'A' grade variant, which TLV2252QDRG4 implements). Over full temperature range (−40°C to 125°C), the max VIO is 1000 µV. Typical value is 200 µV, and temperature coefficient is 0.5 µV/°C.
Can TLV2252QDRG4 drive ADC inputs directly?
Yes, TLV2252QDRG4 can directly drive SAR and delta-sigma ADC inputs due to its rail-to-rail output swing, low output impedance (220 Ω typical), and ability to source/sink ±75 µA while maintaining <100 mV drop. Its 0.187 MHz GBW ensures stable settling for 12-bit conversions at sample rates up to ~10 kSPS.
Is TLV2252QDRG4 pin-compatible with other devices in the TLV225x family?
Yes, TLV2252QDRG4 shares identical 8-pin SOIC (D) pinout with TLV2252IDR, TLV2252AIDR, and TLV2252AQDR - all dual op-amps in the same package. Pin functions (e.g., Pin 1 = IN− A, Pin 2 = IN+ A, Pin 3 = OUT A, etc.) are consistent across these variants, enabling drop-in replacement where temperature and offset specifications align.
