Product details
Overview
TLV2402CDG4 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. Its input common-mode range extends from –0.1 V to VCC + 5 V, enabling use in Li-ion–powered sensor front-ends and low-voltage industrial monitoring systems.
For engineers reviewing the TLV2402CDG4 datasheet, TLV2402CDG4 pinout, TLV2402CDG4 application, or TLV2402CDG4 equivalent, key selection criteria include ultra-low quiescent current, reverse-battery fault tolerance, rail-to-rail I/O swing at sub-3-V operation, input overvoltage capability beyond VCC, and guaranteed performance across 0°C to 70°C commercial temperature range.
Technical Context
The TLV2402CDG4 employs a hybrid PNP/NPN input stage enabling true rail-to-rail input operation and 5-V over-the-rail tolerance-inputs remain functional up to VCC + 5 V without damage. Its output stage uses complementary push-pull architecture to achieve rail-to-rail output swing with ±200 µA drive capability.
Reverse battery protection is implemented via integrated Schottky diode network, limiting reverse supply current to ≤50 nA at –18 V and 25°C. The amplifier maintains DC accuracy with 390 µV typical offset voltage, 120 dB CMRR, and 130 V/mV open-loop gain at 2.7 V, supporting precision DC-coupled signal conditioning.

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2402IDGK | Same electrical specs but rated for –40°C to 125°C industrial temperature range; higher max VIO (1500 µV) applies across full range | Suitable for automotive engine bay or outdoor industrial enclosures where ambient exceeds 70°C | Select when extended temperature operation is required; otherwise TLV2402CDG4 offers cost advantage for commercial environments |
| TLV2242CDGK | Higher supply current (1 µA/ch), same rail-to-rail I/O, no reverse battery protection, 5-kHz GBW | Lacks reverse polarity fault tolerance; requires external protection diode in battery-powered systems | Choose only if reverse battery risk is eliminated by system design; TLV2402CDG4 provides inherent protection with lower ICC |
Compared with TLV2402IDGK, TLV2402CDG4 trades extended temperature range for lower cost and identical micro-power performance in commercial environments; versus TLV2242CDGK, it adds reverse-battery resilience and reduces supply current by 12%, improving battery runtime without sacrificing precision.

FAQ
What is the maximum supply voltage for TLV2402CDG4?
The absolute maximum supply voltage for TLV2402CDG4 is 17 V, with recommended operating range from 2.5 V to 16 V. Operation at 16 V is fully characterized across temperature, and the device maintains rail-to-rail output swing and 880-nA supply current per channel at this voltage. Exceeding 17 V risks permanent damage.
Does TLV2402CDG4 support true rail-to-rail input operation?
Yes, TLV2402CDG4 supports true rail-to-rail input operation with a common-mode range from –0.1 V to VCC + 5 V. This is achieved via a hybrid PNP/NPN input stage that remains functional even when inputs exceed the positive rail by up to 5 V-critical for interfacing with overvoltage sensors or unregulated power sources.
Can TLV2402CDG4 be used with a 2.5-V supply?
Yes, TLV2402CDG4 is fully specified down to 2.5 V and operates reliably at this minimum supply. At 2.5 V, it delivers rail-to-rail output swing, 880-nA supply current per channel, and maintains 5.5-kHz gain bandwidth-making it ideal for single-cell Li-ion (2.7–4.2 V) and alkaline (1.5 V × 2) powered systems.
What is the reverse battery protection capability of TLV2402CDG4?
TLV2402CDG4 provides reverse battery protection up to –18 V. Under reverse supply conditions (–18 V applied to VCC with inputs grounded and outputs open), supply current is limited to ≤50 nA at 25°C. This eliminates the need for external series diodes in battery-powered equipment where incorrect battery installation is possible.
Is TLV2402CDG4 pin-compatible with other dual op-amps in MSOP-8 package?
No, TLV2402CDG4 has a unique pinout optimized for dual-channel operation with shared ground and supply: pins 1/8 are outputs, 2/3/6/7 are inputs, 4 is GND, and 5 is VCC. It is not pin-compatible with generic dual op-amps like LMV358 or TLV2372 in DGK package-layout redesign is required for substitution.
