Product details
Overview
TLV2252IDR from Texas Instruments is a dual rail-to-rail output operational amplifier optimized for low-voltage, micropower applications. It delivers 19 nV/√Hz input voltage noise at 1 kHz, 34 µA per channel supply current, and 850 µV max input offset voltage at 25°C, enabling precision signal conditioning in battery-powered sensor interfaces and portable instrumentation.
For engineers reviewing the TLV2252IDR datasheet, TLV2252IDR pinout, TLV2252IDR application, or TLV2252IDR equivalent, key selection criteria include its rail-to-rail output swing (2.7 V to 8 V supply), ultra-low input bias current (1 pA typ), and guaranteed operation across −40°C to 125°C for industrial and automotive sensing nodes.
Technical Context
The TLV2252IDR uses Advanced LinCMOS™ process technology to achieve high input impedance (>10¹² Ω) and rail-to-rail output capability without external level-shifting circuitry. Its common-mode input voltage range extends to the negative rail, supporting single-supply operation with ground-referenced sensors.
It features a gain-bandwidth product of 0.187 MHz at 3 V and 0.2 MHz at 5 V, with 63° phase margin ensuring stable unity-gain buffer configurations. The device is fully characterized for both 3 V and 5 V operation and supports low-noise small-signal amplification for piezoelectric transducers and high-impedance sources.

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 |
|---|---|---|---|
| TLV2372IDR | Higher supply current (20 µA/channel vs. 34 µA), lower VIO (2 mV max), no rail-to-rail output | Not suitable for 3 V ADC interfacing due to ~1.2 V output headroom limitation | Select when ultra-low power dominates over output swing and precision is secondary |
| OPA2333AIDR | Zero-drift architecture, 0.02 µV/°C VIO drift, 17 µA/channel, higher cost | Required only for sub-µV DC stability in precision weigh scales or strain gauge bridges | Choose only if long-term VIO drift <0.1 µV/month is mandatory; otherwise TLV2252IDR offers better cost/performance balance |
Compared with TLV2252IDR, TLV2372IDR trades rail-to-rail output and higher precision for lower quiescent current, while OPA2333AIDR adds zero-drift stability at significantly higher unit cost and reduced bandwidth-making TLV2252IDR optimal for general-purpose low-voltage, low-noise, rail-to-rail dual op-amp needs.

FAQ
What is the maximum operating temperature range for TLV2252IDR?
The TLV2252IDR is rated for operation from −40°C to +125°C, meeting industrial and automotive under-hood requirements. This range is validated per the recommended operating conditions table in the SLOS185D datasheet, with full electrical characterization across the entire span including input offset voltage, CMRR, and output drive capability.
Does TLV2252IDR support true rail-to-rail input common-mode range?
No, TLV2252IDR supports rail-to-rail *output* swing but its common-mode input voltage range extends only to the negative rail (GND) and up to VDD−1.3 V. For example, at 3 V supply, VICR is 0 V to 1.7 V-not the full 0–3 V range. This is explicitly specified in the "Recommended Operating Conditions" table of the datasheet.
Can TLV2252IDR drive a 10 kΩ load while maintaining rail-to-rail output?
Yes, TLV2252IDR maintains rail-to-rail output swing into loads ≥10 kΩ at room temperature. The datasheet specifies VOH = 2.98 V and VOL = 10 mV at IO = ±20 µA with 3 V supply-well within 10 mV of each rail. Driving heavier loads (e.g., 2 kΩ) degrades swing margin, as shown in Figure 1 (VOH vs. IOH curves).
Is TLV2252IDR pin-compatible with TLV2252CDR or TLV2252AIDR?
TLV2252IDR shares the same SOIC-8 (D) package and pinout as TLV2252CDR and TLV2252AIDR, but differs in input offset voltage grade: TLV2252IDR has 1500 µV max VIO, TLV2252AIDR has 850 µV max, and TLV2252CDR is not defined in the datasheet-TI does not list a C-grade version. All share identical pin functions and layout compatibility.
What PCB layout considerations improve noise performance of TLV2252IDR?
To minimize noise, route TLV2252IDR inputs away from digital traces and clock lines, use local 0.1 µF ceramic decoupling at Pin 5 (VDD+) and Pin 4 (GND), keep feedback resistors ≤100 kΩ to limit Johnson noise, and guard the inverting input node with a grounded trace. These practices are validated in TI's "Op Amp Noise Application Report" (SBAA224) and reflected in the 19 nV/√Hz measured noise floor.
