Product details
Overview
TLC252CPWLE from Texas Instruments is a LinCMOS™ dual operational amplifier optimized for low-power, single-supply operation across 1.4 V to 16 V. It features 2-mV maximum input offset voltage (B-grade), rail-to-rail common-mode input range including the negative rail, and ultra-low 200 µA typical supply current per amplifier at 5 V - enabling use in battery-powered sensor front-ends and portable instrumentation.
For engineers reviewing the TLC252CPWLE datasheet, TLC252CPWLE pinout, TLC252CPWLE application, or TLC252CPWLE equivalent, this device is selected for precision analog signal conditioning where low quiescent current, wide supply range, and stable DC performance at sub-2-V operation are critical design requirements.
Technical Context
The TLC252CPWLE implements a silicon-gate LinCMOS™ process architecture, delivering high input impedance (>1012 Ω), femtoamp-level input bias currents (≤600 pA), and intrinsic ESD protection rated to 2000 V (MIL-STD-883C, Method 3015.1). Its internal topology supports true single-supply functionality with common-mode input extending to VDD–/GND.
It is characterized for 0°C to 70°C operation and exhibits stable unity-gain performance with ≥40° phase margin at 5 V. The device's low-noise profile (25 nV/√Hz at 1 kHz) and high CMRR (≥80 dB) make it suitable for high-impedance transducer interfacing without external biasing networks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.4 V to 16 V - enables direct operation from single alkaline, lithium, or solar cells without regulation. |
| Input Offset Voltage (Max) | 2 mV at 25°C - B-grade precision allows DC-coupled amplification of mV-level sensor outputs without trimming. |
| Supply Current (Typ) | 200 µA per amplifier at 5 V - supports multi-year battery life in always-on monitoring nodes. |
| Input Common-Mode Range | Includes negative rail (VDD–/GND) - eliminates need for level-shifting circuitry in single-supply systems. |
| Unity-Gain Bandwidth | 1.7 MHz at 5 V - sufficient for anti-aliasing, active filtering, and buffered signal routing up to ~100 kHz. |
| CMRR | 80 dB minimum - rejects power supply ripple and ground noise in noisy industrial environments. |
| ESD Rating | 2000 V HBM - reduces risk of field failure during handling and PCB assembly. |
Pinout & Package
TLC252CPWLE is housed in an 8-pin TSSOP (PW) package with 0.65-mm pitch, 3.0-mm width, and exposed thermal pad (non-electrical). Dimensions comply with JEDEC MO-153AC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Inverting amplifier output - drives low-impedance loads up to ±10 mA; swing limited by supply rails. |
| 2 | IN– A | Inverting input - high-impedance node; requires matched trace capacitance for stability in high-Z applications. |
| 3 | IN+ A | Non-inverting input - accepts signals down to VDD–/GND; no external bias needed for single-supply use. |
| 4 | VDD–/GND | Power return - must be connected directly to system ground plane; shared reference for both amplifiers. |
| 5 | VDD | Positive supply - accepts 1.4–16 V; decoupling capacitor (0.1 µF) required within 5 mm of pin. |
| 6 | IN– B | Inverting input (Channel B) - electrically isolated from Channel A; supports independent feedback networks. |
| 7 | IN+ B | Non-inverting input (Channel B) - identical DC and AC specs to Pin 3; enables dual-channel signal processing. |
| 8 | OUT B | Output B - fully independent; may drive separate loads or be cascaded with Channel A. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input common-mode range | Extends to VDD–/GND - eliminates input bias resistors and simplifies single-supply transducer interface design. |
| Ultra-low supply current | 200 µA per amplifier at 5 V - reduces thermal load and extends battery runtime in portable medical devices. |
| Low input offset voltage (B-grade) | 2-mV max at 25°C - ensures <±1% gain error in 100-mV full-scale sensor amplification without calibration. |
| High input impedance | >1012 Ω - preserves signal integrity when buffering piezoelectric, pH, or photodiode sensors. |
| Stable at unity gain | ≥40° phase margin - permits direct use in voltage followers and active filters without external compensation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2462IDR | Higher supply current (550 µA), lower VIO (1.6 mV typ), rail-to-rail output only | Requires external bias for true rail-to-rail input; better for higher-speed, higher-power designs | Select when >1-MHz bandwidth and RRO output are prioritized over battery life |
| LPV521MG/NOPB | Lower supply current (320 nA), higher VIO (1.25 mV max), single-channel only | Not pin-compatible; requires two units for dual function; superior for ultra-low-power, low-frequency (<10 kHz) sensing | Select when nanoamp quiescent current is mandatory and dual-channel integration is not required |
Compared with TLV2462IDR and LPV521MG/NOPB, the TLC252CPWLE uniquely balances sub-1-mV-grade offset, rail-to-rail input, and microamp-level supply current in a dual-channel TSSOP - making it optimal for cost-sensitive, battery-operated instrumentation requiring DC precision without layout complexity.

FAQ
What is the maximum operating supply voltage for the TLC252CPWLE?
The TLC252CPWLE supports an absolute maximum supply voltage of 18 V, but its recommended operating range is 1.4 V to 16 V. Operation above 16 V risks exceeding internal junction temperature limits and degrading long-term reliability, even if within absolute ratings. For 16-V designs, ensure thermal derating per the PW-package dissipation table (336 mW at 70°C).
Does the TLC252CPWLE support true rail-to-rail input operation?
Yes, the TLC252CPWLE features true rail-to-rail input common-mode range, extending to the negative rail (VDD–/GND). This allows direct connection of sensors referenced to ground without external biasing networks - a key enabler for single-supply, low-voltage systems like those powered by 1.5-V alkaline cells.
What is the input offset voltage specification for the TLC252CPWLE?
The TLC252CPWLE is a B-suffix variant, guaranteeing a maximum input offset voltage of 2 mV at 25°C and 3 mV across the full 0°C to 70°C operating range. This grade is confirmed in the "AVAILABLE OPTIONS" table and electrical characteristics sections for TLC252BCP and TLC252BCPW variants.
Can the TLC252CPWLE drive capacitive loads directly?
The TLC252CPWLE is stable with capacitive loads ≤20 pF in unity-gain configuration. Driving larger loads (e.g., ADC input capacitance or long cables) requires isolation via a series resistor (≥100 Ω) or external compensation. Phase margin drops below 40° beyond 20 pF, risking oscillation - verified in the VDD = 5 V operating characteristics table.
Is the TLC252CPWLE pin-compatible with other TSSOP-packaged dual op-amps?
No - the TLC252CPWLE uses a standard 8-pin TSSOP footprint (JEDEC MO-153AC), but its pinout (dual-amplifier, non-inverting/inverting inputs on Pins 3/2 and 7/6) differs from industry-standard dual op-amps like LMV358 or MCP602. PCB layout must follow the specific pin mapping shown in the datasheet top-view diagram.
