Product details
Overview
TLV2252IP from Texas Instruments is a dual rail-to-rail output CMOS operational amplifier optimized for low-voltage, micropower operation. It delivers 19 nV/√Hz input voltage noise at 1 kHz, 1 pA typical input bias current, and 34 µA per channel supply current across a 2.7 V to 8 V supply range. Its common-mode input voltage includes the negative rail and supports single-supply sensor signal conditioning in battery-powered instrumentation.
For engineers reviewing the TLV2252IP datasheet, TLV2252IP pinout, TLV2252IP application, or TLV2252IP equivalent, key selection criteria include rail-to-rail output swing, sub-1 pA input bias current for high-impedance sources, 850 µV max input offset voltage (AI grade), and compatibility with 3 V ADC interfaces in portable medical and environmental monitoring systems.
Technical Context
The TLV2252IP uses Advanced LinCMOS™ process technology to achieve rail-to-rail output swing while maintaining ultra-low input bias current and low noise. Its input stage operates with common-mode voltage extending to the negative rail, enabling direct sensing of ground-referenced signals without level-shifting circuitry.
It is fully characterized at 3 V and 5 V, supporting stable operation across automotive-grade temperature ranges (−40°C to +125°C). The device features internal ESD protection and is specified for both single-supply and split-supply configurations without performance degradation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 8 V - Enables direct use with single-cell Li-ion (3.0–3.7 V) or two-cell alkaline (3.0 V nominal) power rails. |
| Input Bias Current | 1 pA typ - Minimizes loading error on high-impedance piezoelectric or pH sensor outputs. |
| Input Offset Voltage | 850 µV max (TLV2252AI variant) - Supports precision DC-coupled amplification without external trimming. |
| Output Swing | Rail-to-rail - Delivers full dynamic range into ADCs with 0 V to VDD reference, maximizing SNR. |
| Input Voltage Noise | 19 nV/√Hz @ 1 kHz - Low-noise performance critical for amplifying microvolt-level transducer signals. |
| Quiescent Current | 34 µA per channel - Enables multi-year battery life in always-on remote sensors. |

| 2 | IN1− | Inverting input - High-impedance node (10¹² Ω) minimizes signal source loading. |
| 3 | IN1+ | Non-inverting input - Common-mode range extends to VDD−, allowing ground-referenced sensor connection. |
| 4 | GND / VDD− | Negative supply terminal - Serves as reference for single-supply operation; tied to system ground. |
| 5 | VDD+ | Positive supply terminal - Accepts 2.7–8 V; internal regulation ensures stable bias over supply variation. |
| 6 | IN2+ | Non-inverting input (amp 2) - Independent input for differential or dual-channel signal paths. |
| 7 | IN2− | Inverting input (amp 2) - Matches amp 1 characteristics for matched gain stages. |
| 8 | OUT2 | Amplifier 2 output - Fully independent channel; no crosstalk between amplifiers in same package. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-voltage op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2322IP | Higher input offset voltage (2.5 mV max), higher noise (25 nV/√Hz), no rail-to-rail output - limited dynamic range at 3 V. | Legacy design upgrade path only; unsuitable for precision 3 V ADC interfacing. | Select TLV2252IP when rail-to-rail output, lower noise, or tighter VIO is required. |
| OPA2340PA | Rail-to-rail I/O, lower noise (7 nV/√Hz), but higher quiescent current (200 µA/channel) and narrower supply range (2.7–5.5 V). | Better noise performance but incompatible with 8 V industrial supplies or ultra-low-power designs. | Choose OPA2340PA only if noise is dominant constraint and power budget allows ≥200 µA/channel. |
Compared with TLV2322IP and OPA2340PA, TLV2252IP uniquely balances rail-to-rail output, 1 pA input bias, 19 nV/√Hz noise, and 34 µA/channel quiescent current across 2.7–8 V - making it optimal for long-life, high-impedance, single-supply sensor systems where dynamic range and power are co-constrained.

FAQ
What is the maximum operating temperature range for TLV2252IP?
The TLV2252IP is rated for operation from −40°C to +125°C, meeting industrial and automotive-grade thermal requirements. This specification is confirmed in the Absolute Maximum Ratings and Recommended Operating Conditions tables of the official SLOS185D datasheet, and applies to all TLV2252I-grade devices in the P package.
Does TLV2252IP support true rail-to-rail input capability?
No, TLV2252IP provides rail-to-rail *output* swing but its common-mode input voltage range extends only to the negative rail (VDD−) and up to VDD+ −1.3 V. At 3 V supply, this yields a usable input range of 0 V to 1.7 V - sufficient for ground-referenced sensors but not full rail-to-rail input.
Is TLV2252IP pin-compatible with TLV2322IP?
Yes, TLV2252IP and TLV2322IP share identical 8-pin DIP (P) package footprints and pin assignments (OUT1, IN1−, IN1+, GND, VDD+, IN2+, IN2−, OUT2). However, TLV2252IP offers improved specs including rail-to-rail output, lower noise, and lower input offset voltage - making it a functional upgrade without PCB changes.
What is the typical supply current per channel for TLV2252IP at 3 V?
The typical supply current per channel for TLV2252IP is 34 µA at VDD = 3 V and TA = 25°C, as specified in the "Electrical Characteristics" section of the SLOS185D datasheet. Total device current is approximately 68 µA under no-load conditions.
Can TLV2252IP drive capacitive loads directly?
TLV2252IP is stable with capacitive loads up to 100 pF when configured with unity-gain feedback, as verified by phase margin (63°) and gain margin (15 dB) measurements in the datasheet. For larger capacitive loads (>100 pF), external isolation resistance (e.g., 10–50 Ω in series with output) is recommended to maintain stability.
