Product details
Overview
TLV2782AIP from Texas Instruments is a dual rail-to-rail input/output operational amplifier optimized for low-voltage, low-power applications. It operates from 1.8 V to 3.6 V, delivers 8 MHz gain-bandwidth, 4.8 V/µs slew rate at 2.7 V, and consumes only 650 µA per channel - enabling high-speed signal conditioning in battery-powered sensor interfaces and portable data converters.
For engineers reviewing the TLV2782AIP datasheet, TLV2782AIP pinout, TLV2782AIP application, or TLV2782AIP equivalent, this page provides verified electrical specifications, industrial-grade (−40°C to 125°C) performance data, MSOP-8 package details, shutdown behavior, and real-world design context for precision analog front-ends.
Technical Context
The TLV2782AIP implements a CMOS input stage with rail-to-rail input common-mode range (−0.2 V to VDD+0.2 V) and rail-to-rail output swing, supporting single-supply operation down to 1.8 V. Its 8 MHz unity-gain bandwidth and 4.8 V/µs positive slew rate are achieved with just 650 µA/channel supply current - a key efficiency advantage over competing low-voltage op-amps.
It features an active shutdown mode (900 nA/channel typical), internal compensation for stable operation with capacitive loads up to 10 pF, and robust PSRR (75–90 dB) across 1.8–3.6 V supply range - making it suitable for mixed-signal systems where supply noise rejection and fast settling (<2.8 µs to 0.01%) are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 3.6 V - enables direct operation from two rechargeable cells (±0.9 V to ±1.8 V) without voltage boosting. |
| Gain-Bandwidth Product | 8 MHz - supports closed-loop configurations up to ~1 MHz with ≥10× phase margin into 2 kΩ//10 pF. |
| Slew Rate (SR+) | 4.8 V/µs at VDD = 2.7 V - allows full-scale 1-V step response in <210 ns with minimal distortion. | Input Offset Voltage (max) | 2000 µV over −40°C to 125°C - ensures DC accuracy in temperature-variable sensor amplification. |
| Supply Current / Channel | 650 µA typical - enables dual-channel signal conditioning in sub-1.5 mA total system analog budget. |
| Input Noise Voltage | 9 nV/√Hz at 10 kHz - preserves SNR in audio and medium-bandwidth instrumentation paths. |
| Shutdown Current | 900 nA/channel - reduces standby power by >700× versus active mode for intermittent sensing. |
Pinout & Package
TLV2782AIP is housed in an 8-pin MSOP (DGK) package - 3.0 mm × 3.0 mm footprint, 0.65 mm pitch, exposed pad optional - optimized for space-constrained portable designs. Thermal resistance θJA = 259.9°C/W (low-K PCB).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Channel 1 Output | Delivers rail-to-rail swing (within 180 mV of rails at 5 mA load); high-impedance in shutdown. |
| 1IN− | Channel 1 Inverting Input | CMOS input with 2.5 pA bias current; requires short trace routing to minimize stray capacitance. |
| 1IN+ | Channel 1 Noninverting Input | Supports common-mode range from −0.2 V to VDD+0.2 V - enables ground-referenced single-supply sensing. |
| GND | Analog Ground Reference | Single ground pin shared by both channels; must connect to low-inductance ground plane. |
| VDD | Positive Supply Rail | Accepts 1.8–3.6 V; requires local 0.1 µF ceramic + 6.8 µF tantalum decoupling per datasheet layout guidelines. |
| 2IN+ | Channel 2 Noninverting Input | Independent input node; identical specs to 1IN+; no internal cross-coupling in normal operation. |
| 2IN− | Channel 2 Inverting Input | Matches 1IN− performance; supports differential configurations with matched external resistors. |
| 2OUT | Channel 2 Output | Functionally identical to 1OUT; fully independent output stage with same drive capability and shutdown behavior. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-voltage operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2782IDR | Same silicon, SOIC-8 package (4.9 mm × 3.9 mm), 176°C/W θJA, no shutdown pin - pinout differs (SHDN replaced by NC). | Preferred for cost-sensitive industrial PCBs where board area is less constrained and shutdown not required. | Select when MSOP footprint is unnecessary and thermal dissipation margin is sufficient with SOIC layout. |
| OPA2333AIDGKR | Zero-drift architecture (0.02 µV/°C drift), lower VIO (10 µV max), but higher supply current (17 µA/channel) and 350 kHz GBW. | Better for ultra-stable DC-coupled applications (e.g., precision weigh scales), not high-speed AC paths. | Choose only if microvolt-level offset stability outweighs need for 8 MHz bandwidth and 650 µA power budget. |
Compared with TLV2782IDR, TLV2782AIP offers 35% smaller PCB area and integrated shutdown - critical for portable designs; versus OPA2333AIDGKR, it trades offset stability for 23× higher bandwidth and 26× lower quiescent current, targeting speed/power-sensitive applications.

FAQ
What is the maximum recommended supply voltage for TLV2782AIP?
The absolute maximum supply voltage for TLV2782AIP is 4 V, but the recommended operating range is strictly 1.8 V to 3.6 V per the datasheet. Exceeding 3.6 V risks parametric shift or reliability degradation, especially at high temperature. At 3.6 V, the device delivers optimal slew rate (≥4 V/µs) and output drive while maintaining 650 µA/channel supply current.
Does TLV2782AIP support true rail-to-rail input and output operation?
Yes, TLV2782AIP supports rail-to-rail input common-mode range (−0.2 V to VDD+0.2 V) and rail-to-rail output swing (within 180 mV of each rail at 5 mA load). This is confirmed in the datasheet's "Rail-to-Rail Input/Output" feature list and electrical characteristics tables - enabling direct interfacing with 1.8 V ADCs and DACs without external level-shifting circuitry.
What is the shutdown behavior of TLV2782AIP, and how is it controlled?
TLV2782AIP includes an active-low shutdown pin (pin 5, labeled 1SHDN in the DGK pinout). When pulled to GND, supply current drops to 900 nA/channel and outputs enter high-impedance state. The pin may be left floating to enable - but parasitic leakage must be avoided. This behavior is documented in the "Shutdown Characteristics" table and "Shutdown Function" application note section of the TLV2782AIP datasheet.
Can TLV2782AIP drive capacitive loads, and what is the recommended approach?
TLV2782AIP is stable with capacitive loads ≤10 pF when directly connected. For larger loads (e.g., ADC input capacitance >10 pF), TI recommends adding a series null resistor (RNULL) between the op-amp output and load - values from 0 Ω to 50 Ω depending on CL, as shown in Figure 30 of the datasheet. This preserves phase margin and prevents ringing, verified via simulation and bench testing at 25°C and 125°C.
What is the guaranteed input offset voltage specification for TLV2782AIP over temperature?
TLV2782AIP guarantees a maximum input offset voltage of 2000 µV across the full operating temperature range of −40°C to 125°C. This is specified in the "Electrical Characteristics" table under "TLV278xA Full range" condition. At 25°C, typical VIO is 250 µV, with a temperature coefficient of 8 µV/°C - enabling predictable DC error modeling in precision sensor signal chains.
