Product details
Overview
TLC2252CPW from Texas Instruments is a dual rail-to-rail output, very low-power operational amplifier in an 8-pin TSSOP package. It delivers 35 µA per channel supply current, 19 nV/√Hz input voltage noise at 1 kHz, and 1500 µV maximum input offset voltage at 25°C. Designed for single- or split-supply battery-powered signal conditioning, it interfaces directly with precision ADCs in portable instrumentation.
For engineers reviewing the TLC2252CPW datasheet, TLC2252CPW pinout, TLC2252CPW application, or TLC2252CPW equivalent, key selection criteria include micropower operation (≤125 µA total), rail-to-rail output swing (within 20 mV of rails at ±5 V), low input bias current (1 pA typ), and guaranteed performance across 0°C to 70°C.
Technical Context
The TLC2252CPW uses Advanced LinCMOS™ process technology to achieve rail-to-rail output swing while maintaining ultra-low quiescent current. Its input stage supports common-mode voltage down to the negative rail, enabling true single-supply operation with inputs referenced to ground.
It features fully specified performance at both 5 V single-supply and ±5 V split-supply configurations, with CMRR ≥70 dB and PSRR ≥80 dB across temperature. The device includes internal ESD protection and is characterized for dynamic range extension in high-impedance sensor interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 70–125 µA total (35 µA per channel typ) - enables multi-year battery life in always-on sensing nodes |
| Input Offset Voltage | 200–1500 µV max at 25°C - suitable for DC-coupled amplification without trimming in cost-sensitive designs |
| Input Bias Current | 1–60 pA typ - preserves signal integrity from high-impedance sources like piezoelectric transducers |
| Input Voltage Noise | 19 nV/√Hz at 1 kHz - 4× lower than prior-generation micropower CMOS op-amps for cleaner small-signal gain |
| Output Swing | Within 20 mV of both rails at ±5 V - maximizes dynamic range when driving SAR or delta-sigma ADCs |
| Common-Mode Range | Includes negative rail (VDD–/GND) - supports ground-referenced input signals in single-supply systems |
| Gain-Bandwidth Product | 0.2 MHz - sufficient for anti-aliasing filters and sensor signal conditioning up to ~20 kHz |
Pinout & Package
Package: 8-pin TSSOP (PW), 3.0 mm × 4.4 mm body, 0.65 mm pitch, exposed pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Amplifier 1 output - rail-to-rail capable, drives loads ≥10 kΩ |
| 2 | IN1– | Inverting input - high-impedance node (10¹² Ω), sensitive to layout parasitics |
| 3 | IN1+ | Non-inverting input - matches IN1– for optimal CMRR; accepts signals down to VDD– |
| 4 | VDD– / GND | Negative supply or ground reference - must be low-impedance for stable rail-to-rail operation |
| 5 | VDD+ | Positive supply - supports 2.2 V to 8 V single-supply or ±2.2 V to ±8 V dual-supply |
| 6 | IN2+ | Non-inverting input of amplifier 2 - independent channel, identical specs to IN1+ |
| 7 | IN2– | Inverting input of amplifier 2 - matched to IN2+ for consistent AC/DC performance |
| 8 | OUT2 | Amplifier 2 output - fully independent; shares same supply pins and thermal environment as OUT1 |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-power operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC2272CPW | Higher GBW (2.2 MHz), higher supply current (1.3 mA/ch), no rail-to-rail output | Better for higher-frequency active filters; unsuitable where rail-to-rail swing is required | Select TLC2272CPW only when bandwidth >100 kHz is needed and power budget allows 37× higher current |
| TLV2432IPW | Rail-to-rail I/O, 600 µA/ch supply, 22 nV/√Hz noise, wider input voltage range (beyond rails) | Superior drive capability and input flexibility; trades 17× higher current for enhanced performance | Choose TLV2432IPW when interfacing with rail-to-rail ADCs requiring full input-range compatibility and faster settling |
Compared with TLC2252CPW, TLC2272CPW offers higher speed but sacrifices micropower operation and rail-to-rail output, while TLV2432IPW provides full rail-to-rail I/O and stronger output drive at significantly higher quiescent current - making TLC2252CPW the optimal choice for ultra-low-power, rail-to-rail output–constrained designs.

FAQ
What is the maximum supply voltage rating for the TLC2252CPW?
The TLC2252CPW has an absolute maximum supply voltage rating of ±8 V for split-supply operation or 8 V for single-supply operation. Operation beyond these limits risks permanent damage. Recommended operating range is ±2.2 V to ±8 V or 2.2 V to 8 V, with full electrical specifications guaranteed across this span for the C-suffix grade.
Does the TLC2252CPW support true rail-to-rail input operation?
No, the TLC2252CPW supports rail-to-rail *output* swing but its common-mode input voltage range extends only to VDD– and up to VDD+ –1.5 V. For example, at ±5 V supplies, inputs may range from –5 V to +3.5 V. This allows ground-referenced inputs in single-supply use but does not support full rail-to-rail input common-mode range.
Can the TLC2252CPW drive a 10 kΩ load while maintaining rail-to-rail output swing?
Yes, the TLC2252CPW maintains rail-to-rail output swing into loads ≥10 kΩ at ±5 V supply. Data sheet Figures 2 and 3 confirm output voltages within 20 mV of both rails under 50 µA load conditions. Driving lower impedances (e.g., <2 kΩ) reduces swing margin and increases distortion - verify load requirements against the "Maximum Output-Swing Bandwidth" (30 kHz at 2 VPP, RL = 50 kΩ) specification in the TLC2252CPW datasheet.
How does the input offset voltage of the TLC2252CPW compare to the TLC2252AIPW variant?
The TLC2252CPW has a maximum input offset voltage of 1500 µV at 25°C, whereas the TLC2252AIPW (A-grade, industrial temp) specifies 850 µV max at 25°C. Both share the same 0.5 µV/°C temperature coefficient. The A-grade variant is preferred for applications requiring tighter DC accuracy across temperature, such as precision weigh scales or calibrated sensor calibration circuits.
Is the TLC2252CPW pin-compatible with legacy TS27L2 or TLC27L2 devices?
Yes, the TLC2252CPW is pin-compatible with the TS27L2 and TLC27L2 in the 8-pin TSSOP (PW) package. It serves as a direct performance upgrade: offering rail-to-rail output, 4× lower noise (19 vs. ~75 nV/√Hz), lower input offset voltage (1500 µV vs. 2000 µV max), and lower supply current (35 µA/ch vs. 120 µA/ch). No PCB changes are required for drop-in replacement in existing designs.
