Product details
Overview
TLE2022ACP from Texas Instruments is a dual-channel, precision operational amplifier using the Excalibur bipolar process, delivering 2 MHz unity-gain bandwidth, 0.65 V/µs slew rate, and 100 µV max input offset voltage at ±15 V supply. It operates across –55°C to +125°C and supports both single-5V and split-±15V supplies, making it suitable for military-grade sensor signal conditioning in low-power analog front-ends.
For engineers reviewing the TLE2022ACP datasheet, TLE2022ACP pinout, TLE2022ACP application, or TLE2022ACP equivalent, key selection criteria include its phase-reversal protection, rail-to-rail input capability (down to negative rail), low 300 µA max supply current, and stable dc performance over temperature and time-critical for high-accuracy instrumentation and data acquisition systems.
Technical Context
The TLE2022ACP employs Texas Instruments' complementary bipolar Excalibur process with isolated vertical PNP transistors, enabling improved unity-gain bandwidth and slew rate versus legacy OP21-based designs. Its bias circuit ensures minimal parameter drift-only 2 µV/°C offset tempco and 0.006 µV/month long-term drift.
It features phase-reversal protection that prevents output inversion when inputs fall below the negative supply rail, and its common-mode input range includes the negative rail under ±15 V operation (–15 V to +13.2 V), supporting true single-supply interfacing with grounded sensors.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Dual op-amp - enables compact dual-stage amplification or differential pair implementation without external matching. |
| Unity-gain bandwidth | 2 MHz - supports stable closed-loop operation up to ~1.7 MHz at ±15 V (typical), sufficient for anti-aliasing filters and medium-speed sensor interfaces. |
| Slew rate | 0.65 V/µs - ensures <1 µs settling for 1 V step, critical for pulse amplification and fast-settling instrumentation. |
| Input offset voltage | 150 µV max (25°C, ±15 V) - enables sub-1 mV error in 10 V full-scale measurement without trimming. |
| Supply current | 300 µA max per channel - allows dual-amplifier operation within 600 µA total, ideal for battery-powered or thermally constrained modules. |
| Operating temperature | –55°C to +125°C - qualified for MIL-STD-883 Class B environments including avionics, downhole tools, and engine control units. |
| Input bias current | 50 nA max - permits use with high-impedance sources (e.g., piezoelectric sensors, pH electrodes) without significant DC error. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision dual op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OP27GP | Higher slew rate (2.8 V/µs) and bandwidth (8 MHz), but higher supply current (1.2 mA) and no phase-reversal protection. | Better for high-speed active filters; unsuitable where input may go below negative rail without external protection. | Select OP27GP only when speed outweighs power and rail-to-rail input needs. |
| LM158J | Lower cost, wider temp range (–55°C to +125°C), but lower precision: 2 mV VIO max, 0.3 V/µs slew rate, no phase-reversal protection. | Acceptable for non-critical industrial controls; insufficient for metrology-grade measurements. | Choose LM158J for cost-sensitive, non-precision applications where 10× VIO tolerance is acceptable. |
Compared with OP27GP and LM158J, the TLE2022ACP uniquely balances military-grade temperature stability, phase-reversal immunity, and sub-200 µV offset in a low-power dual op-amp-making it irreplaceable in safety-critical sensor interfaces where input fault behavior and long-term calibration integrity are mandatory.

FAQ
What is the maximum supply voltage rating for the TLE2022ACP?
The TLE2022ACP has an absolute maximum supply voltage rating of ±20 V (i.e., VCC+ ≤ +20 V and VCC– ≥ –20 V). Operation beyond these limits risks permanent damage. For reliable long-term use, TI specifies recommended operating conditions of ±2 V to ±20 V, with full electrical characterization validated at ±15 V and 5 V supplies. The TLE2022ACP must never be operated with differential supply exceeding 40 V total.
Does the TLE2022ACP support single-supply operation?
Yes, the TLE2022ACP is explicitly specified for 5 V single-supply operation per datasheet Section 5.3 and Section 5.8. In this configuration, Pin 4 serves as ground (GND), Pin 8 as VCC+, and the common-mode input range extends from 0 V to +3.2 V at 25°C. Its phase-reversal protection remains active, preventing output faults when inputs approach ground-enabling robust interfacing with 0 V-referenced sensors without external level-shifting circuitry.
What is the input offset voltage specification for the TLE2022ACP at room temperature and ±15 V supply?
At 25°C and ±15 V supply, the TLE2022ACP has a maximum input offset voltage (VIO) of 150 µV for the 'M' grade (military-spec), as confirmed in Table 5-10 of the datasheet. Typical value is 70 µV. This specification applies to the TLE2022M variant in CDIP-8 (JG) packaging-the exact configuration denoted by the 'ACP' suffix-and is guaranteed across the full –55°C to +125°C range with a tempco of 2 µV/°C.
How does phase-reversal protection work in the TLE2022ACP?
The TLE2022ACP integrates internal circuitry that actively disables the input differential pair when either input falls below the negative supply rail (VCC–), preventing the output from erroneously inverting polarity-a failure mode common in standard op-amps. This eliminates the need for external Schottky clamping diodes in grounded-sensor applications such as thermocouples or bridge transducers, reducing BOM count and PCB area while improving system reliability during fault conditions.
Is the TLE2022ACP pin-compatible with other dual op-amps in the same package?
No, the TLE2022ACP uses a non-standard pinout for the CDIP-8 (JG) package: Pin 1 = IN– Ch1, Pin 2 = IN+ Ch1, Pin 3 = OUT Ch1, Pin 4 = GND (for single-supply) or VCC– (for split-supply), Pin 5 = IN+ Ch2, Pin 6 = IN– Ch2, Pin 7 = OUT Ch2, Pin 8 = VCC+. It is not pin-compatible with industry-standard dual op-amps like LM358 or TL082, which place power pins at Pins 4 and 8. Layout redesign is required when substituting into existing footprints.
