Product details
Overview
TLV2784AID 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 TLV2784AID datasheet, TLV2784AID pinout, TLV2784AID application, or TLV2784AID equivalent, key selection criteria include its −40°C to 125°C industrial temperature rating, 250 µV max input offset voltage (25°C), shutdown capability with 900 nA/channel quiescent current, and TSSOP-14 package compatibility with space-constrained mixed-signal PCB layouts.
Technical Context
The TLV2784AID implements a CMOS input stage with rail-to-rail common-mode input 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 58° phase margin into 2 kΩ//25 pF loads. Its shutdown function disables all four amplifiers simultaneously via a shared 1/2SHDN and 3/4SHDN control logic.
It features ultralow supply current (650 µA per channel), 2.5 pA typical input bias current, and 18 nV/√Hz input voltage noise at 1 kHz - making it suitable for high-gain, low-noise front-end stages where power efficiency and DC precision are co-critical.
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 rechargeable cells without regulation. |
| Gain-Bandwidth Product | 8 MHz - supports stable unity-gain buffer configurations up to ~8 MHz with minimal phase lag. |
| Slew Rate | 4.8 V/µs at VDD = 2.7 V - ensures <2.4 µs settling to 0.01% for 1 V step, critical for fast ADC driver applications. |
| Input Offset Voltage | 250 µV max at 25°C - reduces DC error in precision sensor amplification and 16-bit+ data converter interfaces. |
| Input Voltage Noise | 9 nV/√Hz at 10 kHz - preserves SNR in audio preamps and low-frequency biosignal conditioning paths. |
| Shutdown Current | 900 nA per channel - extends battery life in intermittent-sampling systems like portable ECG monitors. |
| Operating Temperature | −40°C to 125°C - qualified for under-hood automotive sensors and industrial process controllers. |
Pinout & Package
TSSOP-14 package: 4.4 mm × 5.0 mm body, 0.65 mm pitch, exposed pad not present, RoHS-compliant lead-free finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7, 8, 14 | Output (OUT) | Amplifier outputs - rail-to-rail swing supports full dynamic range utilization of 12–16-bit SAR ADCs. |
| 2, 6, 9, 13 | Inverting Input (IN−) | Differential input node - low 2.5 pA bias current minimizes resistor-induced offset in high-Z transducer interfaces. |
| 3, 5, 10, 12 | Non-inverting Input (IN+) | Differential input node - rail-to-rail VICR (−0.2 V to VDD+0.2 V) allows direct sensing of ground-referenced signals. |
| 4 | GND | Analog ground reference - requires dedicated low-impedance plane to maintain PSRR >70 dB and noise immunity. |
| 11 | VDD | Positive supply - must be decoupled with 0.1 µF ceramic + 6.8 µF tantalum within 0.1 inch of pin. |
| 1/2SHDN (Pin 6) | Shutdown Control (Ch1 & Ch2) | Logic-high enables Channels 1 & 2; logic-low disables both with output in high-Z state. |
| 3/4SHDN (Pin 13) | Shutdown Control (Ch3 & Ch4) | Independent logic control for Channels 3 & 4 - enables selective power gating in multi-channel systems. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables full-scale signal swing from 0 V to VDD in single-supply topologies - eliminates level-shifting circuitry in portable designs. |
| 8 MHz GBW at 650 µA | Delivers high-speed performance with ultra-low quiescent current - 12× lower power than comparable 10 MHz op-amps. |
| 250 µV max VIO (25°C) | Reduces calibration overhead in factory-trimmed sensor modules - maintains accuracy over full industrial temperature range. |
| Independent dual shutdown | Allows dynamic power management of channel pairs - e.g., keep Ch1/Ch2 active for real-time monitoring while sleeping Ch3/Ch4 during idle cycles. |
| 9 nV/√Hz @ 10 kHz | Preserves signal integrity in low-amplitude physiological measurements - meets EN ISO 14117 requirements for ECG front-ends. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2784ID | Same architecture and pinout, but 3000 µV max VIO (25°C) vs. 2000 µV for TLV2784AID - higher initial offset and drift. | Acceptable for non-precision applications like general-purpose signal buffering where calibration is performed post-assembly. | Select TLV2784ID only when cost sensitivity outweighs DC accuracy requirements and temperature stability is secondary. |
| OPA2333AIPW | Zero-drift topology with 0.02 µV/°C drift vs. 8 µV/°C for TLV2784AID; 350 µA/channel vs. 650 µA; 360 kHz GBW vs. 8 MHz. | Better for ultra-low-drift DC applications (e.g., weigh scales), but insufficient bandwidth for fast ADC drivers or audio paths. | Choose OPA2333AIPW when long-term DC stability dominates speed needs; avoid when >1 MHz closed-loop bandwidth is required. |
Compared with TLV2784ID and OPA2333AIPW, TLV2784AID uniquely balances 8 MHz bandwidth, 250 µV offset, and 650 µA/channel consumption - making it optimal for battery-powered, wideband precision signal chains where both speed and DC accuracy matter.

FAQ
What is the maximum supply voltage for TLV2784AID?
The absolute maximum supply voltage for TLV2784AID is 4 V, but the recommended operating range is strictly 1.8 V to 3.6 V. Exceeding 3.6 V risks parametric degradation and reduced reliability, especially at elevated temperatures. Operation at 3.6 V enables full rail-to-rail output swing while maintaining 8 MHz bandwidth and 4.8 V/µs slew rate - verified per SLOS245E datasheet Section 4.
Does TLV2784AID support true rail-to-rail input common-mode range?
Yes, TLV2784AID supports a common-mode input voltage range from −0.2 V to VDD+0.2 V, exceeding the supply rails. This allows direct interface to ground-referenced sensors and bipolar signal sources without external level-shifting. The specification is confirmed in the "Recommended Operating Conditions" table (Section 4) and validated across −40°C to 125°C for the I-suffix grade.
How does the shutdown function operate on TLV2784AID?
TLV2784AID features two independent shutdown controls: Pin 6 (1/2SHDN) disables Channels 1 and 2, while Pin 13 (3/4SHDN) disables Channels 3 and 4. Driving either pin low reduces supply current to 900 nA per channel and places outputs in high-impedance state. Both pins must be pulled high or left floating (with care to avoid leakage-induced false shutdown) to enable operation - detailed in Section 7.7 of the SLOS245E datasheet.
What is the typical input bias current of TLV2784AID?
The typical input bias current of TLV2784AID is 2.5 pA at 25°C, with a maximum of 300 pA across the full −40°C to 125°C range. This ultra-low value minimizes voltage errors in high-impedance sensor interfaces (e.g., pH electrodes or piezoelectric transducers), as confirmed in the "Electrical Characteristics" table (Section 5) under "Input Bias Current".
Is TLV2784AID compatible with standard TSSOP-14 PCB footprints?
Yes, TLV2784AID uses a JEDEC-standard TSSOP-14 package (4.4 mm × 5.0 mm, 0.65 mm pitch) fully compatible with industry-standard TSSOP-14 land patterns. Thermal and electrical performance assumes adherence to TI's layout guidelines: 0.1 µF ceramic decoupling capacitor placed ≤0.1 inch from VDD/GND pins and avoidance of ground plane under input traces - per Section 15 of SLOS245E.
