Product details
Overview
TLV2402IDGKR from Texas Instruments is a dual-channel, rail-to-rail input/output micro-power operational amplifier with reverse battery protection up to 18 V. It delivers 880 nA per channel supply current, 5.5 kHz gain bandwidth, and operates from 2.5 V to 16 V - enabling ultra-low-power sensor signal conditioning in battery-powered industrial monitoring systems.
For engineers reviewing the TLV2402IDGKR datasheet, TLV2402IDGKR pinout, TLV2402IDGKR application, or TLV2402IDGKR equivalent, key selection criteria include its sub-1-µA quiescent current, ±100 mV beyond-rail input capability (–0.1 V to VCC + 5 V), 390 µV typical offset voltage, and guaranteed operation across –40°C to 125°C industrial temperature range.
Technical Context
The TLV2402IDGKR employs a hybrid PNP/NPN input stage enabling true rail-to-rail input operation with over-the-rail tolerance: inputs function normally up to VCC + 5 V by transitioning NPN emitters into diode conduction above VCC, while maintaining stable bias and gain via a secondary PNP pair. Its 5.5 kHz unity-gain bandwidth and 2.5 V/ms slew rate are optimized for DC-coupled, low-frequency precision applications rather than high-speed signal processing.
Reverse battery protection is implemented via integrated Schottky diode structures that limit reverse supply current to <100 nA at 25°C when VCC = –18 V, preventing latch-up or damage during incorrect battery installation - a critical feature for field-deployed portable instrumentation where maintenance access is limited.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current / Ch | 880 nA typical - enables >10-year battery life in coin-cell-powered IoT sensors with duty-cycled wake-up intervals. |
| Input Common-Mode Range | –0.1 V to VCC + 5 V - supports direct sensing of signals exceeding supply rails, e.g., thermocouple outputs referenced to chassis ground. |
| Gain Bandwidth Product | 5.5 kHz - sufficient for anti-aliasing filtering and DC-stable amplification of slow-varying transducer outputs (e.g., strain gauges, RTDs). |
| Input Offset Voltage | 390 µV typical - ensures ≤0.1% error in 4–20 mA loop receivers using 250 Ω shunt resistors at 25°C. |
| Supply Voltage Range | 2.5 V to 16 V - compatible with single Li-ion (2.7–4.2 V), dual alkaline (3–3.6 V), and industrial 12 V rails without external regulation. |
| Operating Temperature | –40°C to 125°C - qualified for under-hood automotive sensors and industrial PLC analog input modules. |
| Reverse Battery Protection | Up to –18 V - prevents catastrophic failure during battery replacement in remote telemetry units with no service technician oversight. |
Pinout & Package
TLV2402IDGKR is housed in an 8-pin MSOP (DGK) package with exposed thermal pad, measuring 3.0 mm × 3.0 mm × 1.0 mm - optimized for space-constrained PCB layouts in handheld test equipment and wearable health monitors.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (OUT A) | Channel A output | Rail-to-rail swing to within 180 mV of rails at 50 µA load - supports direct interface to SAR ADC reference buffers without level-shifting. |
| 2 (IN– A) | Channel A inverting input | Ultra-low 100 pA max input bias current at 25°C - preserves accuracy in megaohm-level feedback networks used in pH electrode amplifiers. |
| 3 (IN+ A) | Channel A non-inverting input | Accepts common-mode voltages up to VCC + 5 V - enables high-side current sensing with single-supply configuration. |
| 4 (GND) | Analog ground reference | Shared return path for both channels; requires dedicated low-impedance ground plane connection to minimize crosstalk and offset drift. |
| 5 (VCC) | Positive supply rail | Supports reverse voltage up to –18 V - eliminates need for external series diode in battery-powered designs, reducing BOM count and forward-drop loss. |
| 6 (IN+ B) | Channel B non-inverting input | Independent, matched input structure to Channel A - enables differential input stages or dual-sensor readout with matched DC performance. |
| 7 (IN– B) | Channel B inverting input | Same ultra-low bias current and over-rail tolerance as Pin 2 - allows identical circuit design for both channels in multi-channel data acquisition. |
| 8 (OUT B) | Channel B output | Electrically isolated output stage - enables independent loading and avoids interaction between channels in shared-load configurations. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables full dynamic range utilization in single-supply systems - eliminates need for dual supplies or level-shifting circuitry in portable medical devices. |
| 880-nA/channel supply current | Reduces average power to <1 µW per channel - extends shelf life and operational runtime in energy-harvesting sensor nodes powered by solar cells or piezoelectric sources. |
| 1500 µV max VIO over full temp range | Guarantees stable DC accuracy across –40°C to 125°C - critical for uncalibrated industrial temperature transmitters operating in wide ambient conditions. |
| 120 dB CMRR at 25°C | Maintains signal integrity in noisy factory environments - rejects common-mode noise from motor drives and switching power supplies coupled onto sensor cables. |
| 5-V over-the-rail input capability | Permits direct connection to external voltage references or sensor outputs floating above VCC - simplifies front-end design in isolated current-loop interfaces. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2402CDGKR | Commercial-grade (0°C to 70°C); otherwise identical electrical specs and pinout. | Limited to indoor consumer electronics and non-automotive industrial enclosures. | Select when ambient temperature remains within 0–70°C and cost sensitivity outweighs extended temperature qualification. |
| LPV821DRX | Lower 650 nA supply current but narrower 1.8 V to 5.5 V supply range; no reverse battery protection. | Suitable only for ultra-low-power wearables with regulated 3.3 V supply and no battery reversal risk. | Choose only if supply voltage is fixed ≤5.5 V and reverse polarity exposure is eliminated by mechanical design or external protection. |
Compared with TLV2402CDGKR, TLV2402IDGKR provides guaranteed operation at –40°C and 125°C for automotive and outdoor deployments; compared with LPV821DRX, it trades 230 nA higher supply current for 18 V reverse battery tolerance and 2.5–16 V supply flexibility - essential for unregulated battery systems.

FAQ
What is the maximum supply voltage for TLV2402IDGKR, and what happens if exceeded?
The absolute maximum supply voltage for TLV2402IDGKR is 17 V. Operation above this rating risks permanent damage due to junction breakdown. The device is specified for reliable operation up to 16 V, with electrical characteristics guaranteed at 2.7 V, 5 V, and 15 V. Exceeding 17 V violates absolute maximum ratings and voids warranty compliance per TI SLOS244B.
Does TLV2402IDGKR support true rail-to-rail input when VCC = 2.5 V?
Yes. TLV2402IDGKR supports rail-to-rail input from –0.1 V to VCC + 5 V across its full supply range. At VCC = 2.5 V, this means inputs operate from –0.1 V to +7.5 V - enabling direct interfacing with external references or sensors biased above the supply rail, even at minimum operating voltage.
Can TLV2402IDGKR drive a 100-kΩ load while maintaining rail-to-rail output swing?
Yes. TLV2402IDGKR guarantees rail-to-rail output swing into loads ≥500 kΩ. When driving a 100-kΩ load, output swing is reduced: at VCC = 5 V, VOH ≥4.92 V and VOL ≤230 mV (IOL = 50 µA), delivering >95% of full-scale range - sufficient for most 12-bit ADC interfaces without additional buffering.
Is TLV2402IDGKR pin-compatible with other dual op-amps in MSOP-8 packages?
No. TLV2402IDGKR uses a non-standard pinout: Pins 1/8 are outputs, Pins 2/3 and 6/7 are inputs, Pin 4 is GND, and Pin 5 is VCC. This differs from industry-standard dual op-amp MSOP-8 layouts (e.g., TLV2372, LMV358), requiring PCB layout revision for substitution - verify pin mapping before redesign.
How does reverse battery protection work in TLV2402IDGKR, and what is the leakage current at –12 V?
TLV2402IDGKR integrates internal Schottky diodes that clamp reverse supply current. At –12 V and 25°C with inputs grounded and outputs open, reverse supply current is typically <50 nA (per datasheet Figure 26). Leakage increases with temperature - at 125°C, it reaches ~200 nA - still well below destructive thresholds and compatible with long-term battery backup operation.
