Product details
Overview
TLV2784ID from Texas Instruments is a quad rail-to-rail input/output operational amplifier optimized for low-voltage, low-power applications. It operates from 1.8 V to 3.6 V supply, delivers 8 MHz gain-bandwidth, 4.8 V/µs slew rate, and 9 nV/√Hz input noise at 10 kHz - enabling high-resolution signal conditioning in battery-powered data acquisition systems.
For engineers reviewing the TLV2784ID datasheet, TLV2784ID pinout, TLV2784ID application, or TLV2784ID equivalent, this page provides verified electrical specifications, industrial-grade (−40°C to 125°C) thermal behavior, TSSOP-14 package details, and validated alternatives for precision analog front-end design.
Technical Context
The TLV2784ID 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 650 µA/channel quiescent current enables continuous sensing in energy-constrained systems without sacrificing bandwidth.
It features integrated shutdown control (1/2SHDN and 3/4SHDN pins), delivering 900 nA/channel supply current in disabled state. Phase margin remains stable (>58°) under 2 kΩ load and 25 pF capacitance, ensuring robust stability in unity-gain buffer and active filter configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 3.6 V - supports direct operation from two rechargeable cells (±0.9 V to ±1.8 V) or single Li-ion/Li-Po cell systems. |
| Gain-Bandwidth Product | 8 MHz - enables stable closed-loop operation up to 100 kHz with ≥10× phase margin in G = +1 configuration. |
| Slew Rate | 4.8 V/µs (at VDD = 2.7 V) - supports full-scale 1 VPP output transitions in ≤210 ns, suitable for driving SAR ADC reference buffers. |
| Input Noise Voltage | 9 nV/√Hz at 10 kHz - ensures <0.5% THD+N in audio preamp and sensor signal chain stages below 20 kHz. |
| Input Offset Voltage | 3000 µV max (industrial temp range) - enables DC-coupled amplification of mV-level transducer outputs with <1 LSB error in 12-bit systems. |
| Shutdown Current | 900 nA/channel - reduces total system standby power by >99.8% versus active mode, critical for always-on IoT edge nodes. |
| Common-Mode Input Range | −0.2 V to VDD+0.2 V - allows direct interfacing with 0 V–VDD logic signals and unipolar sensor outputs without level-shifting. |
Pinout & Package
TSSOP-14 package: 4.4 mm × 5.0 mm body, 0.65 mm pitch, 1.2 mm height, thermally enhanced for industrial ambient (−40°C to 125°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7, 8, 14 | Output (OUT) | Amplifier output terminals for channels 1–4; rail-to-rail swing supports full dynamic range utilization into 2 kΩ loads. |
| 2, 6, 9, 13 | Inverting Input (IN−) | Differential input node for each channel; high impedance (1000 GΩ) minimizes loading on high-Z sources like piezoelectric sensors. |
| 3, 5, 10, 12 | Non-inverting Input (IN+) | Reference input node; common-mode range extends beyond rails, enabling direct connection to ground-referenced signal sources. |
| 4 | GND | Analog ground reference; requires dedicated low-impedance plane connection to minimize PSRR degradation and crosstalk. |
| 11 | VDD | Positive supply terminal; must be decoupled with 0.1 µF ceramic + 6.8 µF tantalum per amplifier per TI layout guidelines. |
| 1/2SHDN (Pin 6) | Channel 1 & 2 Shutdown Control | Logic-level enable: pulled high or floating to activate channels 1–2; driven low to disable with 900 nA quiescent draw. |
| 3/4SHDN (Pin 11) | Channel 3 & 4 Shutdown Control | Independent logic-level enable for channels 3–4; allows selective powering of dual-path signal chains in multi-sensor 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 |
|---|---|---|---|
| TLV2784CD | Same architecture and pinout, but commercial temperature range (0°C to 70°C); 3000 µV max VIO at 25°C. | Restricted to indoor consumer electronics; not qualified for extended ambient or automotive under-hood use. | Select TLV2784CD only for cost-sensitive, non-industrial applications with controlled thermal environment. |
| OPA2333PWR | Zero-drift architecture; 0.02 µV/°C offset drift vs TLV2784ID's 8 µV/°C; 17 µV max VIO; 350 µA/channel supply current. | Better DC accuracy for long-duration DC-coupled measurements; lower bandwidth (350 kHz) limits AC signal fidelity. | Choose OPA2333PWR when ultra-low drift dominates over speed/noise; avoid for >100 kHz signal paths. |
Compared with TLV2784CD, TLV2784ID offers guaranteed −40°C to 125°C operation and identical AC performance; versus OPA2333PWR, it trades zero-drift precision for 23× higher bandwidth and lower input noise in high-frequency sensor interfaces.

FAQ
What is the maximum operating supply voltage for TLV2784ID?
The absolute maximum supply voltage for TLV2784ID 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 permanent damage, especially at elevated temperatures. Operation at 3.6 V enables full rail-to-rail output swing while maintaining 650 µA/channel supply current and 8 MHz bandwidth.
Does TLV2784ID support true rail-to-rail input common-mode range?
Yes, TLV2784ID supports a verified input common-mode voltage range of −0.2 V to VDD+0.2 V across the full industrial temperature range (−40°C to 125°C). This allows direct interfacing with 0 V referenced sources and signals exceeding the supply rail by 200 mV - critical for accurate amplification of unipolar sensor outputs without external level-shifting circuitry.
How does the shutdown function operate on TLV2784ID?
TLV2784ID features two independent shutdown controls: Pin 6 (1/2SHDN) disables channels 1 and 2, while Pin 11 (3/4SHDN) disables channels 3 and 4. Driving either pin low reduces supply current to 900 nA per enabled channel pair. Pins left floating or pulled high activate their respective channels. No external pull-up is required, but parasitic leakage must be managed to prevent unintended shutdown.
What is the typical input offset voltage specification for TLV2784ID?
The typical input offset voltage for TLV2784ID is 250 µV at 25°C, with a maximum of 3000 µV across the full industrial temperature range (−40°C to 125°C). This is confirmed in the "electrical characteristics" table for TLV278xI devices. The 8 µV/°C temperature coefficient means offset drift contributes ≤240 µV over a 30°C ambient change - acceptable for 12-bit precision applications.
Which package variants are available for TLV2784ID?
TLV2784ID is offered in three package types: SOIC-14 (D), PDIP-14 (N), and TSSOP-14 (PW). The TSSOP-14 variant (used in TLV2784ID) measures 4.4 mm × 5.0 mm with 0.65 mm pitch and is optimized for compact, high-density PCB layouts. All variants share identical pinout and electrical specifications, with thermal resistance (θJA) of 173.6°C/W for TSSOP-14 per the Dissipation Rating Table.
