Product details
Overview
TLV2784CPW 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 at 2.7 V, and consumes only 650 µA per channel - enabling high-speed signal conditioning in battery-powered sensor interfaces and portable data acquisition systems.
For engineers reviewing the TLV2784CPW datasheet, TLV2784CPW pinout, TLV2784CPW application, or TLV2784CPW equivalent, key selection criteria include its rail-to-rail I/O swing down to 1.8 V, −40°C to 125°C industrial temperature range (C-suffix variant rated 0°C to 70°C), shutdown capability, and TSSOP-14 package compatibility with space-constrained PCB layouts.
Technical Context
The TLV2784CPW integrates four independent op-amps sharing a common 1.8–3.6 V single-supply rail, each featuring rail-to-rail input common-mode range (−0.2 V to VDD+0.2 V) and rail-to-rail output swing. Its internal architecture supports stable unity-gain operation with 58° phase margin into 2 kΩ//25 pF loads.
Each channel includes an active shutdown control (1/2SHDN and 3/4SHDN pins), reducing supply current to 900 nA/channel when asserted. The device exhibits 9 nV/√Hz input voltage noise at 10 kHz and 0.45% THD+N at AV = 100, f = 10 kHz, making it suitable for precision analog front-ends interfacing with 12-bit+ ADCs.
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 operation up to ~1 MHz with moderate gain (e.g., AV = 8). |
| Slew Rate | 4.8 V/µs at VDD = 2.7 V - allows full-scale 1-V step response in <210 ns, critical for fast-settling DAC buffers. |
| Input Offset Voltage | 3000 µV max (C-temp, 25°C) - ensures ≤3 mV error in unity-gain buffer configurations at room temperature. |
| Supply Current per Channel | 650 µA typical - total quiescent draw of 2.6 mA for all four amplifiers, ideal for always-on sensor signal chains. |
| Input Noise Voltage | 9 nV/√Hz at 10 kHz - low enough to preserve SNR in audio preamps and instrumentation amplifiers driving 24-bit ΣΔ ADCs. |
| Operating Temperature | 0°C to 70°C (C-suffix) - validated for commercial-grade embedded systems including consumer IoT gateways and industrial HMIs. |
Pinout & Package
TSSOP-14 (PW) package: 4.4 mm × 5.0 mm body, 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 | Channel 1 Output | Amplified output node for first op-amp; rail-to-rail swing supports full dynamic range utilization. |
| 2 | Channel 1 Inverting Input | Differential input terminal; high impedance (≥1 GΩ) minimizes loading on feedback networks. |
| 3 | Channel 1 Noninverting Input | Differential input terminal; accepts signals from −0.2 V to VDD+0.2 V, enabling true single-supply sensor interfacing. |
| 4 | Ground (GND) | Common reference for all channels and shutdown logic; must be low-impedance plane for noise immunity. |
| 5 | No Connect (NC) | Internally unconnected; no external connection required or recommended. |
| 6 | Channel 1/2 Shutdown | Active-low enable for Channels 1 & 2; <0.6 V disables both amps, >2 V enables them. |
| 7 | No Connect (NC) | Internally unconnected; no external connection required or recommended. |
| 8 | Positive Supply (VDD) | Single power rail for all four amplifiers; decoupling capacitor (0.1 µF ceramic) required within 0.1 inch. |
| 9 | Channel 2 Output | Amplified output node for second op-amp; identical performance and drive capability as Pin 1. |
| 10 | Channel 2 Inverting Input | Differential input terminal; matched bias current (2.5 pA typ.) enables low-offset differential amplification. |
| 11 | Channel 2 Noninverting Input | Differential input terminal; supports same VICR as Pin 3 for consistent common-mode handling. |
| 12 | Channel 3 Noninverting Input | Differential input terminal for third op-amp; electrically isolated from other channels except shared VDD/GND. |
| 13 | Channel 3 Inverting Input | Differential input terminal for third op-amp; layout symmetry with Pin 10 improves matching in dual-channel designs. |
| 14 | Channel 3/4 Shutdown | Active-low enable for Channels 3 & 4; independent control allows partial system power gating. |

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 |
|---|---|---|---|
| TLV2784IDR | Same electrical specs but rated for −40°C to 125°C industrial temperature range; packaged in tape-and-reel TSSOP-14 (PW). | Required for automotive cabin controllers or outdoor industrial sensors where extended temperature operation is mandatory. | Select TLV2784IDR when ambient operating temperature exceeds 70°C or long-term reliability under thermal cycling is critical. |
| OPA2333PWR | Zero-drift architecture (0.02 µV/°C drift), lower offset (10 µV max), but higher supply current (17 µA/ch) and 350 kHz GBW - not speed-compatible. | Suitable for ultra-precision DC-coupled applications like weigh scales or medical instrumentation where offset stability outweighs bandwidth needs. | Choose OPA2333PWR only when microvolt-level offset drift over temperature is required; avoid for AC-coupled or high-speed signal paths. |
Compared with TLV2784IDR, the TLV2784CPW offers identical performance in a commercial temperature grade at lower cost, while the OPA2333PWR trades bandwidth and power for superior DC precision - making TLV2784CPW optimal for cost-sensitive, medium-speed, battery-operated systems.

FAQ
What is the maximum supply voltage for TLV2784CPW?
The absolute maximum supply voltage for TLV2784CPW 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 is fully characterized and supported across the 0°C to 70°C range.
Does TLV2784CPW support true rail-to-rail input common-mode range?
Yes, TLV2784CPW supports a common-mode input voltage range from −0.2 V to VDD+0.2 V, verified across the full 0°C to 70°C temperature range. This allows direct interfacing with transducers and sensors whose output may go slightly below ground or above VDD, such as piezoelectric elements or certain bridge configurations.
How does the shutdown function work on TLV2784CPW?
TLV2784CPW features two independent shutdown pins: Pin 6 controls Channels 1 and 2, and Pin 14 controls Channels 3 and 4. Driving either pin below 0.6 V disables the corresponding pair, reducing per-channel supply current to 900 nA. Pins can be left floating to enable, but external pull-up resistors are recommended to prevent parasitic leakage-induced shutdown.
Can TLV2784CPW drive capacitive loads without oscillation?
TLV2784CPW is stable for capacitive loads ≤10 pF with direct connection. For larger loads (e.g., ADC input capacitance or long traces), a series resistor (RNULL) of 10–50 Ω between output and load is required to maintain ≥58° phase margin and prevent ringing. Layout best practices - including short traces and local 0.1 µF decoupling - are essential for stability.
What is the typical input bias current of TLV2784CPW?
The typical input bias current for TLV2784CPW is 2.5 pA at 25°C, with a maximum of 100 pA across the full 0°C to 70°C range. This ultra-low bias current minimizes voltage errors in high-impedance sensor interfaces, such as photodiode transimpedance amplifiers or pH electrode buffers, where leakage would otherwise dominate signal accuracy.
