Product details
Overview
TLE2426CLPE3 from Texas Instruments is a precision rail-splitter IC that generates a stable virtual ground at exactly half the input supply voltage (VO = VI/2) for single-supply analog systems. It delivers ±20 mA output current, draws only 170 µA typical supply current at 5 V, operates from 4 V to 40 V input, and provides 7.5 mΩ typical output impedance - enabling high-fidelity signal termination in data acquisition front ends, portable instrumentation, and op-amp biasing circuits.
For engineers reviewing the TLE2426CLPE3 datasheet, TLE2426CLPE3 pinout, TLE2426CLPE3 application, or TLE2426CLPE3 equivalent, this device is selected when precise mid-rail generation, micropower operation, low-noise performance with optional CNR filtering, and TO-92 space-constrained packaging are required - especially where discrete resistor-divider + op-amp solutions introduce drift, noise, or board-area overhead.
Technical Context
The TLE2426CLPE3 integrates a micropower operational amplifier with a laser-trimmed resistive divider on a single die, ensuring a fixed VO/VI ratio of 0.5 across its full 4 V–40 V input range. Its architecture enables simultaneous sourcing and sinking of up to 20 mA while maintaining sub-±250 µV output regulation over load and temperature.
Unlike standard op-amp-based splitters, it features internal trimming for initial output tolerance better than 1% at 5 V or 12 V, and achieves ripple rejection exceeding 12-bit accuracy. The LP package omits the noise-reduction (CNR) pin found in 8-pin variants, simplifying layout but retaining core regulation and stability performance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage Accuracy | ±0.025 V at VI = 5 V (±1% error); ensures reliable mid-rail reference for 10-bit+ ADCs without calibration. |
| Supply Current | 170 µA typ at VI = 5 V; enables battery-powered operation for >1 year in low-duty-cycle sensor nodes. |
| Input Voltage Range | 4 V to 40 V; supports wide-input industrial rails (e.g., 24 V systems) and automotive 12 V with headroom. |
| Output Current Capability | ±20 mA typ; drives multiple op-amp inputs or small-signal stages without external buffering. |
| Output Impedance | 7.5 mΩ typ at DC; maintains stable virtual ground under dynamic load transients in active filter designs. |
| Temperature Coefficient | 25 ppm/°C max (full range); contributes <±0.5 mV drift from −40°C to 85°C at 5 V input. |
| Output Noise (rms) | 30 µV rms (10 Hz–10 kHz, CNR = 1 µF); meets low-noise audio and precision sensor signal-chain requirements. |
Pinout & Package
Package: TO-92 (LP), 3-terminal through-hole plastic package. Compact footprint (4.7 mm × 3.6 mm × 10.2 mm), lead-free tin (Sn) finish, RoHS compliant, rated for 0°C to 70°C operation (C-suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT) | Output terminal | Delivers precision VI/2 voltage; low-impedance node for analog ground connection or op-amp reference. |
| 2 (COMMON) | Ground reference | System ground return path; must be connected directly to PCB ground plane for optimal regulation. |
| 3 (IN) | Positive supply input | Accepts unregulated DC input (4–40 V); internal circuitry derives and regulates mid-rail independently of input ripple. |
Key Features
| Feature | Design Value |
|---|---|
| Precision rail-splitting | Fixed VO/VI = 0.5 ratio with laser-trimmed divider; eliminates manual calibration and resistor matching errors. |
| Micropower operation | 170 µA typical supply current enables use in always-on, energy-harvested, or coin-cell-powered systems. |
| High output drive | ±20 mA sourcing/sinking capability supports driving multiple downstream analog stages without external buffers. |
| Low output impedance | 7.5 mΩ typical output impedance ensures minimal voltage shift under load changes in active filter or bias networks. |
| Wide input range | 4 V–40 V operation accommodates legacy 5 V, modern 12 V, and industrial 24 V/36 V supply rails. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar rail-splitting applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM334Z | Adjustable current source (not voltage reference); requires external resistor network to generate VI/2; no integrated op-amp or trimming. | Suitable only for low-current biasing (<1 mA); lacks regulation, noise filtering, and load drive capability of TLE2426CLPE3. | Select LM334Z only for ultra-low-cost, non-critical biasing where ±5% accuracy and no load regulation are acceptable. |
| LT6600-10 | Fixed 10 MHz bandwidth amplifier with 0.1% gain accuracy; not a rail splitter - requires external feedback to implement VI/2. | Used in active filter design, not virtual ground generation; higher power (2.5 mA), larger SO-8 package, no built-in trimming. | Choose LT6600-10 only when simultaneous filtering and splitting are needed, and board space/power budget allow. |
Compared with LM334Z and LT6600-10, the TLE2426CLPE3 delivers turnkey VI/2 generation with factory-trimmed accuracy, micropower consumption, and robust ±20 mA drive - making it uniquely suited for space- and power-constrained analog signal chains where discrete alternatives increase BOM count and thermal drift.

FAQ
What is the primary function of the TLE2426CLPE3?
The TLE2426CLPE3 is a precision rail-splitter IC that generates a stable output voltage equal to exactly one-half the input supply voltage (VO = VI/2). It serves as a virtual ground reference in single-supply analog circuits, eliminating the need for external resistor dividers and op-amps. Its monolithic design ensures accuracy, low drift, and high output drive - critical for ADC references, op-amp biasing, and sensor signal conditioning in the TLE2426CLPE3 application space.
Does the TLE2426CLPE3 require external components to operate?
No, the TLE2426CLPE3 is a fully self-contained 3-terminal device requiring no external resistors, capacitors, or op-amps for basic rail-splitting operation. A bypass capacitor (0.1 µF) is recommended at the IN pin for stability, and an optional 1 µF capacitor on the CNR pin would apply - but the LP package used in TLE2426CLPE3 does not include a CNR pin. Therefore, TLE2426CLPE3 operates reliably with just input supply, ground, and load connection.
What is the operating temperature range of the TLE2426CLPE3?
The TLE2426CLPE3 is specified for operation from 0°C to 70°C (commercial temperature range), denoted by the "C" suffix in its part number. This range is validated per TI's SLOS098D datasheet, with full electrical performance guaranteed across this interval - including output voltage accuracy, regulation, and supply current. Derating is not required within this span, and the device is qualified for continuous use in ambient environments meeting this specification.
Can the TLE2426CLPE3 replace a discrete resistor-divider + op-amp circuit?
Yes - the TLE2426CLPE3 is explicitly designed as a drop-in replacement for discrete resistor-divider + op-amp virtual ground circuits. It integrates laser-trimmed resistors and a micropower op-amp on one die, delivering superior initial accuracy (±1% at 5 V), lower temperature drift (25 ppm/°C), and consistent ±20 mA drive - all in a TO-92 package smaller than most op-amp SOICs. Unlike discrete solutions, TLE2426CLPE3 avoids resistor tolerance stacking, op-amp input offset, and thermal tracking errors.
Is the TLE2426CLPE3 pin-compatible with other TLE2426 variants?
No - the TLE2426CLPE3 uses the 3-pin TO-92 (LP) package with OUT-COMMON-IN pinout, whereas D (SOIC-8), P (PDIP-8), and JG (CERDIP-8) variants have 8 pins and include a dedicated noise-reduction (CNR) pin. Pin compatibility exists only among LP-packaged variants (e.g., TLE2426CLP, TLE2426CLPR, TLE2426CLPE3), all sharing identical 3-pin topology and mechanical footprint. Substituting an 8-pin variant requires PCB redesign.
