Product details
Overview
TLE2022ACPE4 from Texas Instruments is a dual-channel, bipolar precision operational amplifier optimized for low-power, high-speed signal conditioning in single-supply (5V) and split-supply (±15V) systems. It delivers 2.8MHz gain-bandwidth, 0.65V/µs slew rate, 100µV max input offset voltage, and operates across 0°C to 70°C. It is used in analog input modules for industrial sensor interfaces where rail-to-rail input capability and phase-reversal protection are critical.
For engineers reviewing the TLE2022ACPE4 datasheet, TLE2022ACPE4 pinout, TLE2022ACPE4 application, or TLE2022ACPE4 equivalent, key selection criteria include its 300µA max supply current, ±15V/5V dual-supply compatibility, 19nV/√Hz input voltage noise at 10Hz, and PDIP-8 package with verified pin functions for dual op-amp channel routing.
Technical Context
The TLE2022ACPE4 employs Texas Instruments' complementary bipolar process with isolated vertical PNP transistors, enabling improved unity-gain bandwidth and slew rate over legacy OP21-based designs. Its bias circuit ensures stable DC parameters over time and temperature.
It features phase-reversal protection to prevent output inversion when inputs fall below the negative rail, and supports common-mode input voltage ranges extending to the negative rail - making it suitable for single-supply low-level signal amplification without level-shifting circuitry.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2277PA | Lower offset (10µV max), higher supply current (800µA), SOIC-8 only | Better DC accuracy but incompatible with through-hole PDIP layout; requires PCB redesign | Select when ultra-low offset dominates over power and package constraints |
| TL072CP | Higher noise (18nV/√Hz typ), no phase-reversal protection, 3mV offset max | Cost-optimized general-purpose dual op-amp - unsuitable for precision sensor front-ends requiring rail-to-rail input or fault tolerance | Select only for non-critical AC-coupled or high-frequency applications where offset stability is secondary |
Compared with OPA2277PA and TL072CP, the TLE2022ACPE4 uniquely balances low power (300µA), precision (100µV offset), phase-reversal immunity, and PDIP-8 compatibility - making it optimal for drop-in upgrades in legacy analog input modules and field-deployed instrumentation.

FAQ
What is the maximum supply voltage rating for the TLE2022ACPE4?
The TLE2022ACPE4 has an absolute maximum supply voltage of ±20V across VCC+ and VCC– terminals. For reliable operation, TI specifies recommended dual-supply ranges of ±2V to ±15V or single-supply operation from +4V to +40V. Exceeding these limits risks permanent damage, and thermal derating must be applied above 70°C ambient.
Does the TLE2022ACPE4 support true rail-to-rail output swing?
No, the TLE2022ACPE4 does not provide rail-to-rail output swing. Under ±15V supply and 10kΩ load, output swings to ±14.3V (typical), and under +5V single supply, it swings from ~0.7V to ~4.3V. Its key rail-related strength is rail-to-rail *input* common-mode range - including the negative rail - not output voltage compliance.
How does the phase-reversal protection in the TLE2022ACPE4 function?
The TLE2022ACPE4 integrates internal circuitry that clamps input differential voltage and disables output stage conduction when either input falls below VCC– by more than ~0.6V. This prevents the unexpected polarity inversion seen in unprotected op-amps during sensor disconnection or overvoltage faults - a documented behavior confirmed in TI's SLVSJD7A datasheet Section 3.
Is the TLE2022ACPE4 pin-compatible with other TLE2022 variants like TLE2022CP or TLE2022IDR?
Yes, all TLE2022 variants - including TLE2022ACPE4, TLE2022CP, and TLE2022IDR - share identical pinouts for their respective packages. The TLE2022ACPE4 (PDIP-8) matches the pin configuration of TLE2022CP (also PDIP-8), while TLE2022IDR uses SOIC-8 with same signal mapping but different physical footprint - requiring PCB layout change.
What is the typical input bias current specification for the TLE2022ACPE4 at 25°C?
The TLE2022ACPE4 exhibits a typical input bias current of 33nA at 25°C under ±15V supply, with a maximum of 70nA across the full 0°C to 70°C operating range. This value is confirmed in Section 6.8 of the SLVSJD7A datasheet and reflects the bipolar input stage's inherent current draw - lower than JFET-input op-amps but well-suited for medium-impedance sensor interfaces.
