Product details
Overview
TLC252BCP from Texas Instruments is a LinCMOS™ dual operational amplifier optimized for low-power, single-supply operation with 2-mV maximum input offset voltage (VIO), 1.4 V to 16 V supply range, and rail-to-rail common-mode input extending to the negative rail - enabling precision signal conditioning in battery-powered sensor interfaces and portable instrumentation.
For engineers reviewing the TLC252BCP datasheet, TLC252BCP pinout, TLC252BCP application, or TLC252BCP equivalent, this device is selected for ultra-low quiescent current (3 µA typical at 5 V), high input impedance (>10¹² Ω), and stable unity-gain performance in energy-constrained analog front-ends where offset drift and supply headroom are critical.
Technical Context
The TLC252BCP implements a silicon-gate LinCMOS™ process delivering inherently low input bias current (≤60 pA) and temperature-stable offset (1.8 µV/°C max), with internal ESD protection rated to 2000 V per MIL-STD-883C Method 3015.1. Its architecture supports true single-supply operation without level-shifting circuitry.
It features two independent amplifiers sharing a common 8-pin DIP package, each with fully differential inputs, open-collector-compatible output stage, and guaranteed stability at unity gain across the full 0°C to 70°C commercial temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VIO max | 2 mV at 25°C - enables accurate DC-coupled amplification without trimming in low-gain sensor signal chains |
| Supply voltage | 1.4 V to 16 V - supports direct operation from single alkaline, Li-ion, or solar cells without regulation |
| Input common-mode range | Extends to VDD–/GND - eliminates need for input biasing networks in ground-referenced transducer interfaces |
| IDD (two amps) | 3 µA typical at 5 V - extends battery life in always-on monitoring systems beyond 10 years on CR2032 |
| Unity-gain bandwidth | 1.7 MHz at VDD = 5 V - sufficient for anti-aliasing, active filtering, and buffered reference distribution |
| CMRR | 80 dB min at 25°C - rejects power supply ripple and shared-noise coupling in mixed-signal PCBs |
| ESD rating | 2000 V HBM - reduces field failure risk during manual handling and board assembly |
Pinout & Package
Package: 8-pin plastic DIP (P), 0.3-inch wide body, through-hole mount. RoHS-compliant lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Output of Amplifier 1 (1OUT) | Push-pull output capable of sourcing/sinking ≥1 mA into 10-kΩ load at VDD = 5 V |
| 2 | Inverting input of Amplifier 1 (1IN–) | Differential input node with ≤60 pA bias current - suitable for high-Z feedback networks |
| 3 | Non-inverting input of Amplifier 1 (1IN+) | High-impedance input referenced to GND or negative rail - enables rail-to-rail sensing |
| 4 | Ground / Negative Supply (VDD–/GND) | Common return for both amplifiers and external circuitry - must be low-impedance for noise immunity |
| 5 | Positive Supply (VDD) | Single-supply rail accepting 1.4–16 V - decoupling capacitor required within 1 cm of pin |
| 6 | Output of Amplifier 2 (2OUT) | Independent output stage electrically isolated from 1OUT - allows dual-path signal processing |
| 7 | Inverting input of Amplifier 2 (2IN–) | Matched input characteristics to Pin 2 - supports matched dual-channel configurations |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2462CP | Higher supply current (550 µA), lower VIO (0.5 mV), rail-to-rail output only | Better DC accuracy but 180× higher IDD - unsuitable for multi-year battery life | Select when precision outweighs power; avoid for >1-year battery operation |
| LMV358M/NOPB | Lower cost, wider temp range (–40°C to 125°C), higher VIO (7 mV), no LinCMOS™ input stage | Acceptable for non-critical industrial controls but lacks sub-100-pA bias for high-Z sensors | Select for automotive-adjacent or extended-temp use where input impedance >10⁹ Ω suffices |
Compared with TLV2462CP and LMV358M/NOPB, the TLC252BCP uniquely balances ultra-low power (3 µA), LinCMOS™ input impedance (>10¹² Ω), and 2-mV VIO - making it irreplaceable in long-life, high-impedance sensor nodes where leakage and offset directly impact measurement integrity.

FAQ
What is the maximum operating temperature range for the TLC252BCP?
The TLC252BCP is characterized for operation from 0°C to 70°C, meeting commercial-grade specifications. It is not rated for extended industrial (–40°C to 125°C) or automotive temperature ranges. Thermal derating begins above 70°C, and absolute maximum junction temperature is 150°C - sustained operation near this limit requires careful PCB thermal design and power dissipation management for the TLC252BCP.
Does the TLC252BCP support rail-to-rail output swing?
No, the TLC252BCP does not provide rail-to-rail output swing. At VDD = 5 V, its output typically swings from ~0.05 V above GND to ~3.8 V below VDD under 10-kΩ load. However, its input common-mode range does include the negative rail (GND), enabling true single-supply operation with grounded sensors - a key differentiator of the TLC252BCP versus standard bipolar op-amps.
Can the TLC252BCP be used with a 1.5-V alkaline battery without regulation?
Yes, the TLC252BCP operates down to 1.4 V supply voltage, making it compatible with fresh 1.5-V alkaline cells. At 1.5 V, it maintains functionality with reduced output swing and bandwidth but retains specified VIO (2 mV max) and input bias current (<60 pA). This capability is explicitly validated in the datasheet and defines a core use case for the TLC252BCP in long-life consumer and medical devices.
How does the TLC252BCP differ from the TLC252CP and TLC252ACP variants?
The TLC252BCP has a maximum input offset voltage of 2 mV at 25°C, tighter than the TLC252CP (10 mV) and TLC252ACP (5 mV). All share identical pinout, package, and electrical architecture. The 'B' suffix denotes the highest-precision grade within the TLC252 family, making the TLC252BCP optimal for applications demanding minimal DC error without external trimming - a distinction confirmed across all operating conditions in the official SLOS002I datasheet for the TLC252BCP.
Is the TLC252BCP pin-compatible with newer TI op-amps like the TLV2462?
No, the TLC252BCP is not pin-compatible with the TLV2462 series. While both are dual op-amps in 8-pin packages, the TLV2462 uses SOIC-8 (PW) or TSSOP-8 (DGK) footprints - not the 0.3-inch DIP (P) package of the TLC252BCP. Electrical differences (e.g., rail-to-rail output, higher supply current) and physical incompatibility mean direct replacement requires PCB redesign. The TLC252BCP remains the only LinCMOS™ dual op-amp offered in through-hole DIP packaging.
