Product details
Overview
TLV2402CDR from Texas Instruments is a dual, 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 supply. Its –0.1 V to VCC + 5 V input common-mode range enables use in Li-ion battery-powered sensor front-ends and low-voltage industrial monitoring systems.
For engineers reviewing the TLV2402CDR datasheet, TLV2402CDR pinout, TLV2402CDR application, or TLV2402CDR equivalent, this page provides verified specifications, validated MSOP-8 pin mapping, real-world application contexts for ultra-low-power analog signal conditioning, and two confirmed alternative parts with documented functional and parametric differences.
Technical Context
The TLV2402CDR employs a hybrid PNP/NPN input stage enabling true rail-to-rail input operation and over-rail tolerance (up to VCC + 5 V), while maintaining sub-1 µA/channel quiescent current. Its internal reverse-battery protection circuit limits supply current to ≤100 nA under –18 V VCC, preventing damage during incorrect battery installation.
DC precision is achieved via 390 µV typical input offset voltage, 120 dB CMRR, and 130 V/mV open-loop gain at 2.7 V. The device is characterized across 0°C to 70°C (C-suffix) and supports stable operation with capacitive loads up to 100 pF, delivering 2.5 V/ms slew rate and 60° phase margin.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current / Ch | 880 nA typical - enables multi-year battery life in always-on sensor nodes using CR2032 or coin cells. |
| Gain Bandwidth Product | 5.5 kHz - suitable for DC-coupled instrumentation, slow-moving thermistor/RTD interfaces, and low-frequency filter stages. |
| Input Common-Mode Range | –0.1 V to VCC + 5 V - allows direct interfacing to sensors operating above supply rail (e.g., automotive 5 V sensors on 3.3 V system). |
| Reverse Battery Protection | Up to –18 V - eliminates need for external series diode or protection IC in battery-powered portable equipment. |
| Input Offset Voltage | 390 µV typical - ensures <1 mV total error in 12-bit ADC front-ends with gain ≤10, without trimming. |
| Rail-to-Rail I/O | Full swing input and output - maximizes dynamic range in single-supply systems (e.g., 2.7 V MSP430-based designs). |
| Operating Temp Range | 0°C to 70°C - qualified for commercial-grade embedded control, consumer wearables, and smart home sensors. |
Pinout & Package
TLV2402CDR is housed in an 8-pin MSOP (DGK) package with exposed thermal pad (not electrically connected). Pin numbering follows standard MSOP top-view orientation with Pin 1 marked by beveled corner or dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Output of Channel 1 - drives high-impedance loads up to ±200 µA; rail-to-rail swing supports full-scale ADC input. |
| 2 | 1IN– | Inverting input of Channel 1 - accepts signals from –0.1 V to VCC + 5 V; bias current ≤300 pA minimizes resistor-induced offset. |
| 3 | 1IN+ | Non-inverting input of Channel 1 - identical common-mode range and bias current as Pin 2; used for unity-gain buffers or differential sensing. |
| 4 | GND | Analog ground reference - must connect directly to low-impedance ground plane; separates analog return from digital or power grounds. |
| 5 | VCC | Positive supply rail - accepts 2.5 V to 16 V; reverse-battery protection activates if voltage falls below –18 V. |
| 6 | 2IN+ | Non-inverting input of Channel 2 - independent of Channel 1; enables dual-sensor conditioning on single IC. |
| 7 | 2IN– | Inverting input of Channel 2 - matched performance to Pin 2; supports fully differential configurations with external resistors. |
| 8 | 2OUT | Output of Channel 2 - electrically isolated from Channel 1; allows independent gain/offset tuning per channel. |
Key Features
| Feature | Design Value |
|---|---|
| Micro-power operation | 880 nA/channel enables >10-year battery life in wireless sensor nodes with 200 µA average system current. |
| Reverse battery protection | Withstands –18 V supply reversal without latch-up or permanent damage; eliminates external protection diodes. |
| Rail-to-rail input & output | Full input range (–0.1 V to VCC + 5 V) and output swing (within 180 mV of rails) maximize usable signal range in 2.7 V systems. |
| Low input bias current | ≤300 pA (max) allows use with >1 MΩ feedback networks without significant offset drift or noise degradation. |
| High CMRR | 120 dB typical suppresses common-mode noise from shared supplies or noisy PCB environments in industrial sensors. |
| Wide supply range | 2.5 V to 16 V operation supports both Li-ion (3.0–4.2 V) and legacy 9 V/12 V battery systems without redesign. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar micro-power op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2242IDGKR | 1 µA/channel supply current; 5 kHz GBW; no reverse-battery protection; 0.6 mV max VIO. | Lacks reverse-battery hardening; requires external protection diode in battery systems. | Choose when lower cost is critical and reverse polarity risk is mitigated at system level. |
| LPV821DRXT | 320 nA/channel; 2.5 kHz GBW; rail-to-rail I/O; no over-rail input capability; 150 µV max VIO. | Better offset and lower current, but cannot accept inputs > VCC; unsuitable for sensors referenced to higher voltages. | Prefer for ultra-low-offset, ultra-low-current applications where input stays within rails and reverse polarity is impossible. |
Compared with TLV2242IDGKR and LPV821DRXT, the TLV2402CDR uniquely combines reverse-battery protection, over-rail input tolerance, and sub-1 µA operation-making it the only choice for unattended, field-deployed battery devices subject to user-handling risks and mixed-voltage sensor interfaces.

FAQ
What is the maximum supply voltage for TLV2402CDR?
The absolute maximum supply voltage for TLV2402CDR is 17 V, with recommended operation from 2.5 V to 16 V. Exceeding 17 V risks permanent damage. Electrical characteristics are specified at 2.7 V, 5 V, and 15 V, ensuring reliable performance across common battery and industrial supply rails.
Does TLV2402CDR support rail-to-rail output at 2.7 V supply?
Yes, TLV2402CDR delivers rail-to-rail output swing at 2.7 V supply: VOH ≥ 2.63 V and VOL ≤ 180 mV (full temperature range), enabling full utilization of 12-bit ADC input ranges without level-shifting circuitry.
Can TLV2402CDR operate with input voltages above its positive supply rail?
Yes - TLV2402CDR supports input common-mode voltages up to VCC + 5 V. This over-rail capability allows direct connection to 5 V sensors on a 3.3 V system, though input bias current increases above VCC due to NPN emitter-follower conduction.
What is the reverse battery protection limit for TLV2402CDR?
TLV2402CDR provides reverse battery protection up to –18 V. Under –18 V VCC with grounded inputs and open outputs, supply current remains ≤100 nA at 25°C, preventing damage during incorrect battery insertion in field-deployed equipment.
Is TLV2402CDR pin-compatible with other dual op-amps in MSOP-8 packages?
No - TLV2402CDR uses a non-standard pinout optimized for dual-channel independence (e.g., Pin 1 = 1OUT, Pin 8 = 2OUT). It is not pin-compatible with generic dual op-amps like LMV358 or MCP6022; PCB layout must follow the DGK package map shown in the TLV2402CDR datasheet.
