Product details
Overview
TLC252BCDRG4 from Texas Instruments is a LinCMOS™ dual operational amplifier optimized for low-power, single-supply operation with 2-mV max input offset voltage (VIO), 1.4-V to 16-V supply range, and rail-to-rail common-mode input extending to the negative rail - ideal for battery-powered sensor signal conditioning and portable instrumentation.
For engineers reviewing the TLC252BCDRG4 datasheet, TLC252BCDRG4 pinout, TLC252BCDRG4 application, or TLC252BCDRG4 equivalent, this page delivers verified electrical specs, package mapping, real-world use cases, and validated alternative options for precision analog design under tight power budgets.
Technical Context
The TLC252BCDRG4 implements a silicon-gate LinCMOS™ process enabling ultra-low input bias current (≤60 pA at 25°C) and stable VIO grading (2 mV max), supporting high-impedance transducer interfaces without passive compensation. Its unity-gain stability and true single-supply capability eliminate need for split rails in portable systems.
It features internal ESD protection rated to 2000 V (MIL-STD-883C, Method 3015.1), operates across 0°C to 70°C, and maintains functional performance down to 1.4 V supply - making it suitable for solar-powered and energy-harvesting applications where supply headroom is minimal.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VIO max | 2 mV at 25°C - enables precision DC-coupled amplification without trimming in low-offset sensor front-ends |
| Supply voltage range | 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 - allows ground-referenced input signals in single-supply configurations |
| IDD (two amps) | 3 µA typ at 1.4 V, 25°C - extends battery life in always-on monitoring nodes |
| Unity-gain bandwidth | 1.7 MHz at VDD = 5 V - sufficient for anti-aliasing, active filtering, and moderate-speed signal conditioning |
| Input bias current | ≤60 pA at 25°C - preserves signal integrity in high-Z pH probes, photodiode, or piezoelectric sensor circuits |
| ESD rating | 2000 V HBM - reduces risk of field failure during handling and PCB assembly |
Pinout & Package
Package: SOIC-8 (D package), tape-and-reel (R suffix), RoHS-compliant plastic body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives loads up to 10 kΩ while maintaining linearity near supply rails |
| 2 | IN– A | Inverting input A - high-impedance node (≥10¹² Ω) for feedback network connection |
| 3 | IN+ A | Non-inverting input A - accepts signals down to GND in single-supply mode |
| 4 | VDD–/GND | Ground reference - serves as return path for both amplifiers and bias networks |
| 5 | VDD | Positive supply - accepts 1.4–16 V; no external decoupling required for basic operation |
| 6 | OUT B | Amplifier B output - independent channel for dual-path signal processing or differential drive |
| 7 | IN– B | Inverting input B - electrically isolated from IN– A; supports separate feedback topologies |
| 8 | IN+ B | Non-inverting input B - identical input structure to IN+ A; enables matched dual-channel designs |
Key Features
| Feature | Design Value |
|---|---|
| LinCMOS™ process technology | Delivers femtoamp-level input currents and stable VIO over temperature without laser trimming |
| True single-supply operation | Eliminates need for dual supplies or level-shifting circuitry in portable and remote sensing systems |
| Rail-to-rail input common-mode range | Accepts inputs at GND potential - critical for interfacing with unipolar sensors and ADC references |
| Low-noise performance | 25 nV/√Hz at 1 kHz (high-bias version) - preserves SNR in low-level analog signal chains |
| Stable at unity gain | Enables direct use in voltage followers and active filters without external compensation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC272BCD | Higher VIO (3 mV max), higher supply current (1.2 mA typ), same SOIC-8 package | Better slew rate (3.6 V/µs) but unsuitable for sub-10-µA power budgets | Select when higher speed and drive strength outweigh ultra-low-power requirements |
| LPV521MG/NOPB | Lower supply current (320 nA), lower VIO (1.25 mV), SC-70-5 (single amp), not pin-compatible | Requires PCB redesign; superior for nanoamp-sensor interfaces but lacks dual-channel integration | Choose for lowest possible IDD where dual-channel consolidation is not mandatory |
Compared with TLC272BCD and LPV521MG/NOPB, the TLC252BCDRG4 uniquely balances 2-mV VIO, 3-µA IDD, and dual-channel SOIC-8 integration - making it optimal for space-constrained, battery-operated systems requiring two matched, low-drift amplifiers without layout revision.

FAQ
What is the maximum input offset voltage specification for TLC252BCDRG4?
The TLC252BCDRG4 has a maximum input offset voltage (VIO) 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 of the SLOS002I datasheet, where "B-Suffix Versions Offer 2-mV VIO", and is validated in electrical characteristics tables for TLC252BC variants at VDD = 5 V and 10 V.
Does TLC252BCDRG4 support true single-supply operation with input signals at ground?
Yes, the TLC252BCDRG4 supports true single-supply operation with its common-mode input voltage range extending to the negative rail (VDD–/GND). Per the "recommended operating conditions" table, VIC includes 0 V at all tested supply voltages (1.4 V, 5 V, 10 V, 16 V), enabling direct interface with ground-referenced sensors and transducers without level-shifting circuitry.
What is the typical supply current for TLC252BCDRG4 at 1.4 V supply?
At VDD = 1.4 V and TA = 25°C, the TLC252BCDRG4 draws a typical supply current (IDD) of 300 µA for both amplifiers - confirmed in the "electrical characteristics at specified free-air temperature, VDD = 1.4 V" table under the TLC252_C column. This value reflects operation with no load and VO = 0.2 V, meeting ultra-low-power design goals for energy harvesting systems.
Is TLC252BCDRG4 pin-compatible with other devices in the TLC25x2 family?
Yes, the TLC252BCDRG4 shares identical SOIC-8 (D) pinout and footprint with all members of the TLC252, TLC25L2, and TLC25M2 families, including TLC252CD, TLC252ACD, TLC25L2BCD, and TLC25M2BCD. The pin configuration diagram on page 1 of the SLOS002I datasheet applies universally across these variants, enabling drop-in substitution within the same suffix group.
What packaging and reel specifications apply to TLC252BCDRG4?
TLC252BCDRG4 is supplied in 8-pin SOIC (D package), tape-and-reel format, with "R" denoting reel packaging and "G4" indicating RoHS-compliant green molding compound. Per the datasheet note: "The D package is available taped and reeled. Add the suffix R to the device type (e.g., TLC252CDR)", confirming TLC252BCDRG4 follows this standard reel configuration for automated SMT assembly.
