Product details
Overview
TLV2784CPWR from Texas Instruments is a quad rail-to-rail input/output operational amplifier optimized for low-voltage, low-power precision signal conditioning. 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 9 nV/√Hz input voltage noise at 10 kHz - enabling high-resolution data acquisition in battery-powered instrumentation and portable medical sensors.
For engineers reviewing the TLV2784CPWR datasheet, TLV2784CPWR pinout, TLV2784CPWR application, or TLV2784CPWR equivalent, key selection criteria include its 1.8 V minimum supply, −40°C to 125°C industrial temperature range, TSSOP-14 package footprint, shutdown capability per channel pair, and verified rail-to-rail I/O performance across full supply and common-mode ranges.
Technical Context
The TLV2784CPWR 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 while maintaining 8 MHz bandwidth and 650 µA/channel quiescent current. Its internal architecture includes independent shutdown control for channels 1/2 and 3/4, enabling dynamic power management in multi-channel sensor front-ends.
It features 2.5 pA typical input bias current, 250 µV max input offset voltage (A-grade), and 58° phase margin into 2 kΩ//25 pF loads - ensuring stable unity-gain follower and active filter configurations without external compensation. The device meets industrial-grade reliability with specified operation from −40°C to 125°C and 150°C maximum junction temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 3.6 V - enables direct operation from two alkaline or Li-ion cells; supports ±0.9 V to ±1.8 V split supplies. |
| Gain-Bandwidth Product | 8 MHz - sustains stable closed-loop gain ≥10 up to ~800 kHz; sufficient for anti-aliasing filters and ADC driver stages. |
| Slew Rate | 4.8 V/µs at VDD = 2.7 V - supports 1 VPP signals up to ~760 kHz without distortion in unity-gain buffer configuration. |
| Input Noise Voltage | 9 nV/√Hz at 10 kHz - low enough for 16-bit SAR ADC front-ends with ≤100 kHz signal bandwidth. |
| Input Offset Voltage | 250 µV max (A-grade) - ensures ≤0.01% gain error in 10 V full-scale precision amplification at room temperature. |
| Shutdown Current | 900 nA/channel - reduces total system standby power to <4 µA for all four op-amps, critical for always-on sensor nodes. |
| Common-Mode Input Range | −0.2 V to VDD+0.2 V - accepts inputs beyond rails, simplifying level-shifting in mixed-supply systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2784IPW | Same die, industrial-grade (−40°C to 125°C), identical electrical specs and pinout; differs only in temperature screening and test conditions. | No functional difference; suitable for same applications requiring extended temperature operation. | Select TLV2784IPW when full industrial temperature qualification and traceability are required for automotive or industrial deployments. |
| MCP6004-E/ST | Lower bandwidth (1 MHz), higher input offset (1.5 mV), no shutdown function; 14-lead TSSOP package with identical footprint but different pin mapping. | Lacks dual shutdown control and high-speed capability; not suitable for precision, low-noise, or dynamically powered systems. | Choose MCP6004-E/ST only for cost-sensitive, non-critical DC-coupled applications where speed and noise are not limiting factors. |
Compared with TLV2784CPWR, TLV2784IPW offers identical performance with certified industrial temperature validation, while MCP6004-E/ST trades bandwidth, noise, and power control for lower cost - making TLV2784CPWR the optimal choice for precision, low-voltage, and power-aware designs.

FAQ
What is the maximum recommended supply voltage for TLV2784CPWR?
The absolute maximum supply voltage for TLV2784CPWR 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 degradation and reduced long-term reliability, even if the device appears functional at 3.8 V. Always maintain VDD within 1.8–3.6 V for guaranteed rail-to-rail performance and thermal stability.
Does TLV2784CPWR support true rail-to-rail input common-mode range?
Yes, TLV2784CPWR supports a verified rail-to-rail input common-mode range from −0.2 V to VDD+0.2 V across the full temperature range. This is confirmed in the "recommended operating conditions" table and validated by Figure 1–2 showing input offset voltage vs VICR. It enables direct interfacing with sensors whose outputs swing below ground or above VDD, such as bridge-based transducers.
How does the shutdown function work on TLV2784CPWR?
TLV2784CPWR has two independent shutdown controls: Pin 8 (1/2SHDN) disables channels 1 and 2, and Pin 14 (3/4SHDN) disables channels 3 and 4. Each is active-high: pulling the pin ≥2 V (at VDD = 2.7–3.6 V) or ≥0.75VDD (at VDD = 1.8 V) enables the pair; pulling ≤0.6 V disables it. Supply current drops to 900 nA per channel in shutdown, and outputs enter high-impedance state.
What is the typical input bias current of TLV2784CPWR?
The typical input bias current of TLV2784CPWR is 2.5 pA at 25°C, with a maximum of 100 pA over the full commercial temperature range (0°C to 70°C). This ultra-low value is enabled by its CMOS input stage and makes the device suitable for high-impedance sensor interfaces like photodiodes and piezoelectric elements where leakage current would otherwise dominate error budgets.
Can TLV2784CPWR drive capacitive loads without oscillation?
TLV2784CPWR is stable for capacitive loads ≤10 pF with no series resistance. For loads >10 pF, a series null resistor (RNULL) is required at the output - typically 10–50 Ω - to maintain ≥58° phase margin, as shown in Figure 30 of the datasheet. Driving 100 pF directly will cause ringing or oscillation; adding RNULL restores stability while preserving bandwidth for most sensor interface applications.
