Product details
Overview
TLV2784AIDRG4 from Texas Instruments is a quad rail-to-rail input/output operational amplifier optimized for ultra-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, and 9 nV/√Hz input voltage noise at 10 kHz, with ±10 mA output drive capability - ideal for battery-powered data acquisition front-ends in portable medical sensors and industrial IoT nodes.
For engineers reviewing the TLV2784AIDRG4 datasheet, TLV2784AIDRG4 pinout, TLV2784AIDRG4 application, or TLV2784AIDRG4 equivalent, key selection criteria include its −40°C to 125°C industrial temperature rating, 250 µV max input offset voltage (A-grade), integrated shutdown control per channel pair, and TSSOP-14 package compatibility with high-density PCB layouts.
Technical Context
The TLV2784AIDRG4 implements a CMOS input stage enabling 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. Its 8 MHz unity-gain bandwidth and 4.8 V/µs positive slew rate are achieved with only 650 µA per channel supply current.
It features dual independent shutdown controls (pins 8 and 15) enabling selective channel disabling to reduce system power - each controlling two amplifiers (1/2SHDN and 3/4SHDN). Input bias current is 2.5 pA typical, and input offset voltage drift is 8 µV/°C, supporting stable DC-coupled sensing over 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 rechargeable cells without regulation. |
| Gain-Bandwidth Product | 8 MHz - supports stable closed-loop gain ≥10 up to ~800 kHz with adequate phase margin. |
| Slew Rate | 4.8 V/µs (positive), 4.2 V/µs (negative) at VDD = 3.6 V - ensures <2.4 µs settling to 0.01% for 1 V step with CL = 10 pF. |
| Input Offset Voltage | 250 µV max at 25°C (A-grade) - reduces DC error in precision transducer interfaces and 12-bit+ ADC drivers. |
| Input Noise Voltage | 9 nV/√Hz at 10 kHz - preserves SNR in audio preamps and sensor signal chains with bandwidth ≤100 kHz. |
| Shutdown Current | 900 nA per channel - cuts quiescent power by >99.8% versus active mode (650 µA), critical for intermittent-sampling systems. |
| Operating Temperature | −40°C to +125°C - qualified for under-hood automotive, factory-floor PLCs, and outdoor edge devices. |
Pinout & Package
TSSOP-14 package (4.4 mm × 5.0 mm, 0.65 mm pitch), thermally enhanced with exposed pad (not electrically connected), RoHS-compliant, moisture sensitivity level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 3, 5, 12 | Amplifier Output | Four independent buffered outputs; rail-to-rail swing supports full dynamic range into 2 kΩ loads. |
| 2, 4, 6, 11 | Inverting Input | Differential inputs with 2.5 pA bias current; matched layout minimizes offset in differential configurations. |
| 7, 9, 13, 14 | Non-inverting Input | Rail-to-rail common-mode range (−0.2 V to VDD+0.2 V) allows direct connection to grounded sensors. |
| 8 | 1/2 Channel Shutdown | Logic-high (>2 V) enables channels 1 & 2; logic-low (<0.6 V) disables both and places outputs in high-Z. |
| 15 | 3/4 Channel Shutdown | Independent control for channels 3 & 4 - enables flexible power gating in multi-stage analog signal paths. |
| 10 | GND | Analog ground reference; requires low-impedance connection to minimize noise coupling between channels. |
| 16 | VDD | Single positive supply; decoupling with 0.1 µF ceramic capacitor within 0.1 inch is mandatory for stability. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-Rail I/O | Enables full-scale signal swing from 0 V to VDD in single-supply systems, eliminating level-shifting circuitry. |
| Ultra-Low Supply Voltage | 1.8 V minimum operation extends battery life in coin-cell or energy-harvesting applications. |
| Low Input Bias Current | 2.5 pA typical allows high-impedance sensor interfacing (e.g., pH electrodes, piezoresistive bridges) without significant error. |
| Integrated Dual Shutdown | Two independent enable pins reduce system-level power management complexity and PCB routing. |
| Industrial Temp Grade | −40°C to +125°C operation ensures reliability in uncontrolled environments without thermal derating. |

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 |
|---|---|---|---|
| TLV2784IDR | Same pinout and electrical specs, but 3000 µV max input offset (I-grade vs A-grade); 650 µA supply current unchanged. | Acceptable for AC-coupled or less precise DC applications where offset drift <3 mV over temperature is tolerable. | Select when cost sensitivity outweighs 12-bit+ DC accuracy requirements and industrial temp range is still needed. |
| OPA2333PAIDR | Zero-drift architecture; 0.02 µV/°C offset drift vs 8 µV/°C; higher 350 nV/√Hz noise; 17 µA/ch supply current. | Superior long-term DC stability for precision weigh scales or calibration equipment; unsuitable for low-noise audio or fast settling. | Choose for µV-level DC accuracy over time/temperature; avoid when <1 µA shutdown or <10 nV/√Hz noise is required. |
Compared with TLV2784IDR, TLV2784AIDRG4 provides tighter initial offset for higher-resolution DC measurement; compared with OPA2333PAIDR, it trades zero-drift stability for 27× lower quiescent current and 40× lower broadband noise - making it optimal for battery-constrained, medium-accuracy signal chains.

FAQ
What is the maximum recommended supply voltage for TLV2784AIDRG4?
The absolute maximum supply voltage for TLV2784AIDRG4 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 high temperatures. Operation at 3.6 V enables full 4.8 V/µs slew rate and 8 MHz bandwidth while maintaining 650 µA per channel supply current.
Does TLV2784AIDRG4 support true rail-to-rail input common-mode range?
Yes, TLV2784AIDRG4 supports a verified rail-to-rail input common-mode voltage range of −0.2 V to VDD+0.2 V, confirmed across the full −40°C to +125°C temperature range. This allows direct interfacing with grounded sensors and reference voltages without external level-shifting components, unlike many competing amplifiers limited to VDD−1.2 V.
How does the shutdown function operate on TLV2784AIDRG4?
TLV2784AIDRG4 has two dedicated shutdown pins: pin 8 (1/2SHDN) disables amplifiers 1 and 2, and pin 15 (3/4SHDN) disables amplifiers 3 and 4. Driving either pin below 0.6 V places the corresponding pair into ultra-low-current state (900 nA/channel) with outputs in high-impedance mode. Pulling the pin above 2 V restores full operation with 800 ns turn-on time.
What is the typical input offset voltage specification for TLV2784AIDRG4?
The TLV2784AIDRG4 is an "A-grade" device with a maximum input offset voltage of 250 µV at 25°C and 3000 µV over the full −40°C to +125°C range. Typical offset is 250 µV, and temperature coefficient is 8 µV/°C - significantly tighter than the standard TLV2784IDR (3000 µV max at 25°C), making it suitable for 12-bit+ precision applications.
Can TLV2784AIDRG4 drive capacitive loads directly?
TLV2784AIDRG4 is not unity-gain stable with capacitive loads >10 pF. For loads exceeding 10 pF, a series resistor (RNULL) must be placed between the output and load capacitance to maintain phase margin >58°. Recommended RNULL values range from 0 Ω (for CL ≤ 10 pF) to 50 Ω (for CL = 100 pF) with RL = 2 kΩ, as validated in Figure 18 of the SLOS245E datasheet.
