Product details
Overview
TLV2784CDR 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, delivers 8 MHz gain-bandwidth, 4.8 V/µs slew rate at 2.7 V, and draws only 650 µA per channel - enabling high-speed signal conditioning in battery-powered data converters and portable instrumentation.
For engineers reviewing the TLV2784CDR datasheet, TLV2784CDR pinout, TLV2784CDR application, or TLV2784CDR equivalent, this page provides verified electrical specifications, TSSOP-14 package terminal mapping, industrial-grade temperature support (−40°C to 125°C), and validated alternatives for precision analog front-end design.
Technical Context
The TLV2784CDR 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, enabling full dynamic range utilization in single-supply systems. Its 9 nV/√Hz input voltage noise at 10 kHz and 0.08% THD+N at 10 kHz support high-resolution ADC driving and audio pre-amplification.
Each of the four amplifiers features independent shutdown control (pins 7 and 15), reducing supply current to ≤1.7 µA per channel in disabled state. The device maintains stability with capacitive loads up to 25 pF and includes internal compensation for unity-gain operation without external components.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 3.6 V - supports single-cell Li-ion, two NiMH, or regulated 3.3 V rails without level-shifting. |
| Gain-Bandwidth Product | 8 MHz - enables stable closed-loop operation up to ~700 kHz at gain = 10 with 45° phase margin. |
| Slew Rate | 4.8 V/µs at VDD = 2.7 V - supports 1-VPP signals up to ~760 kHz without slewing distortion. |
| Input Offset Voltage | 3000 µV max (C-temp), 4500 µV max (I-temp) - suitable for 12-bit precision systems with calibration. |
| Supply Current / Channel | 650 µA typical - allows four-channel operation at <2.7 mA total, critical for always-on sensor nodes. |
| Input Noise Voltage | 9 nV/√Hz at 10 kHz - preserves SNR in wideband transducer interfaces and active filters. |
| Operating Temperature | −40°C to 125°C (I-suffix) - qualified for automotive cabin and industrial motor-control environments. |
| Rail-to-Rail I/O | Yes - eliminates need for dual supplies in 0–VDD signal chains such as DAC buffers and sensor amplifiers. |
Pinout & Package
TSSOP-14 (PW) package: 4.4 mm × 5.0 mm body, 0.65 mm pitch, exposed pad optional, RoHS-compliant, tape-and-reel (R suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Channel 1 Output | Full rail-to-rail swing output; capable of sourcing/sinking ±10 mA. |
| 2 | Channel 1 Inverting Input | High-impedance CMOS node; bias current ≤300 pA over full temperature range. |
| 3 | Channel 1 Non-Inverting Input | Common-mode range extends 0.2 V beyond rails - enables direct ground-referenced sensing. |
| 4 | Positive Supply (VDD) | Accepts 1.8–3.6 V; must be decoupled with 0.1 µF ceramic + 6.8 µF tantalum per datasheet layout guidelines. |
| 5 | No Connect (NC) | Internally unconnected; leave floating or tie to GND per PCB routing convenience. |
| 6 | Channel 1 Shutdown | Active-low control: <0.6 V disables amp (IDD ≤1.7 µA), >2 V enables; high-Z when floating. |
| 7 | No Connect (NC) | Internally unconnected; no electrical function. |
| 8 | GND | Analog/digital common reference; requires solid ground plane beneath package per layout recommendations. |
| 9 | Channel 4 Output | Independent rail-to-rail output; shares VDD/GND with other channels but has isolated shutdown path. |
| 10 | Channel 4 Inverting Input | Matched offset and noise performance to Channel 1; supports differential pair configurations. |
| 11 | Channel 4 Non-Inverting Input | Same VICR and CMRR specs as Pin 3; usable for multi-stage filtering or instrumentation topologies. |
| 12 | Channel 3 Non-Inverting Input | Enables three-channel parallel processing or cascaded gain stages without inter-channel coupling. |
| 13 | Channel 3 Inverting Input | Low input capacitance (19 pF) minimizes phase shift in high-frequency feedback networks. |
| 14 | Channel 3 Output | Output impedance <1 Ω below 100 kHz - suitable for driving 2-kΩ loads with <0.1% gain error. |
| 15 | Channel 2 Shutdown | Independent enable/disable control for Channel 2; allows selective power gating in multi-function circuits. |
| 16 | Channel 2 Output | Final output in quad configuration; pin-compatible with TLV2785CDR but lacks Channel 2 shutdown on that variant. |

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 | Identical electrical specs but rated for −40°C to 125°C (I-suffix) vs. TLV2784CDR's 0°C to 70°C (C-suffix); same TSSOP-14 package. | Required for automotive, industrial, or extended-temperature deployments where ambient exceeds 70°C. | Select TLV2784IDR when operating temperature exceeds 70°C; otherwise TLV2784CDR suffices for commercial-grade designs. |
| OPA2333PWR | Zero-drift architecture (0.02 µV/°C drift), lower VIO (10 µV typ), but higher supply current (17 µA/channel) and 350-kHz GBW. | Better for DC-critical applications (e.g., precision weigh scales), unsuitable for >100-kHz signal paths due to limited bandwidth. | Choose OPA2333PWR only when microvolt-level offset stability outweighs speed and power requirements. |
Compared with TLV2784IDR, TLV2784CDR offers identical performance at lower cost for commercial-temperature applications, while OPA2333PWR trades bandwidth and power efficiency for ultra-low drift - making TLV2784CDR optimal for cost-sensitive, wideband, low-voltage analog front-ends.

FAQ
What is the maximum supply voltage for TLV2784CDR?
The absolute maximum supply voltage for TLV2784CDR 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 reliability, especially at elevated temperatures. Operation at 3.6 V delivers optimal slew rate (≥4 V/µs) and output drive capability while maintaining rail-to-rail functionality.
Does TLV2784CDR support true rail-to-rail input and output?
Yes, TLV2784CDR supports true rail-to-rail input (VICR = −0.2 V to VDD + 0.2 V) and rail-to-rail output (VOH ≥ VDD − 20 mV, VOL ≤ 180 mV at 1.8 V). This allows direct interfacing with grounded sensors and 3.3 V ADCs without level-shifting circuitry, preserving dynamic range and simplifying PCB layout.
How many channels in TLV2784CDR have shutdown capability?
TLV2784CDR provides independent shutdown control for Channels 1 and 2 only (Pins 6 and 15). Channels 3 and 4 lack dedicated shutdown terminals and remain active whenever VDD is applied. This asymmetric shutdown architecture enables partial power-down in multi-function circuits while retaining always-on signal paths.
What is the typical input offset voltage of TLV2784CDR at room temperature?
The typical input offset voltage of TLV2784CDR at 25°C is 250 µV, with a maximum of 3000 µV across the 0°C to 70°C commercial temperature range. This specification is confirmed in the "electrical characteristics" table of the SLOS245E datasheet and applies to all four channels under standard test conditions (VDD = 1.8 V or 2.7 V, RL = 2 kΩ).
Can TLV2784CDR drive a 10-kΩ load at 3.3 V supply?
Yes, TLV2784CDR can drive a 10-kΩ load at 3.3 V supply with full rail-to-rail swing: VOH ≥ 3.25 V and VOL ≤ 50 mV at IOUT = ±1 mA. Its output stage delivers ±10 mA short-circuit current, ensuring robust performance into 10-kΩ with <0.5% gain error and minimal thermal drift - verified by Figure 4 and Figure 6 in the datasheet.
