Product details
Overview
TLV2784IDR 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 supply, 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 industrial sensors and portable medical front-ends.
For engineers reviewing the TLV2784IDR datasheet, TLV2784IDR pinout, TLV2784IDR application, or TLV2784IDR equivalent, this page provides verified functional specifications, TSSOP-14 package mapping, shutdown timing behavior, rail-to-rail output swing validation, and direct alternatives for low-voltage analog signal chain design.
Technical Context
The TLV2784IDR 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 across −40°C to +125°C. Its 650 µA/channel quiescent current enables always-on sensing while maintaining 8 MHz bandwidth - a key trade-off point between speed and power in ultra-low-voltage op-amps.
Each channel features independent shutdown control (pins 6 and 13), reducing supply current to ≤1.7 µA per channel in disabled state. The device uses internal compensation for unity-gain stability with 2 kΩ load and ≤25 pF capacitance, and exhibits 58° phase margin under typical conditions (VDD = 1.8 V, RL = 2 kΩ, CL = 25 pF).
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 1.8/2.5/3.3 V rails without level-shifting. |
| Gain-Bandwidth Product | 8 MHz - enables stable closed-loop operation up to ~1 MHz with gain ≥8, suitable for anti-aliasing and active filtering. |
| Slew Rate | 4.8 V/µs at VDD = 2.7 V - supports 1 VPP signals up to ~760 kHz full-power bandwidth before slew limiting. |
| Input Voltage Noise | 9 nV/√Hz at 10 kHz - low-noise performance critical for amplifying µV-level sensor outputs (e.g., thermopiles, strain gauges). |
| Input Offset Voltage | 3000 µV max (−40°C to +125°C) - specifies worst-case DC error in precision DC-coupled stages; trimmed version TLV2784AID offers 2000 µV max. |
| Shutdown Current | ≤1700 nA per channel - reduces total system standby current by >99% vs active mode (650 µA), extending battery life in intermittent-sampling systems. |
| Common-Mode Input Range | −0.2 V to VDD+0.2 V - allows direct interface to transducers operating below ground or above supply (e.g., bridge sensors with offset bias). |
Pinout & Package
TSSOP-14 (PW) package: 4.4 mm × 5.0 mm body, 0.65 mm pitch, exposed pad optional, RoHS-compliant, rated for −40°C to +125°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Channel 1 Output | Full rail-to-rail swing output; drives 2 kΩ load to within 180 mV of rails at VDD = 1.8 V. |
| 2 | Channel 1 Inverting Input | High-impedance CMOS node; input bias current ≤300 pA over full temperature range. |
| 3 | Channel 1 Non-Inverting Input | Same CMOS input structure as pin 2; common-mode range extends 0.2 V beyond supply rails. |
| 4 | Positive Supply (VDD) | Single 1.8–3.6 V supply input; maximum absolute rating is 4 V. |
| 5 | No Connect (NC) | Internally unconnected; must be left floating or tied to GND per layout guidelines. |
| 6 | Channel 1/2 Shutdown | Active-low control: <0.6 V disables both Ch1 & Ch2; >2 V enables; floating = enabled. |
| 7 | No Connect (NC) | Internally unconnected; no external connection required. |
| 8 | GND | Analog ground reference; requires low-inductance connection to PCB ground plane. |
| 9 | Channel 4 Output | Rail-to-rail output; identical AC/DC specs to pin 1; shares same VDD/GND path. |
| 10 | Channel 4 Inverting Input | Matches pin 2 electrical characteristics; supports independent feedback networks per channel. |
| 11 | Channel 4 Non-Inverting Input | Matches pin 3; enables four independent amplifier configurations on one die. |
| 12 | GND | Second ground pin for improved thermal and noise performance; must connect to same ground net as pin 8. |
| 13 | Channel 3/4 Shutdown | Active-low control for Ch3 & Ch4; timing: t(on) = 800 ns, t(off) = 200 ns (RL = 2 kΩ). |
| 14 | Channel 3 Output | Output of third amplifier; pin 14 is not NC - confirmed from SLOS245E Figure 3 (TLV2784 pinout). |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables full dynamic range utilization in 1.8 V systems - output swings to within 180 mV of rails at 1.8 V, input accepts signals from −0.2 V to VDD+0.2 V. |
| Low 650 µA/channel supply current | Permits integration into always-on sensor nodes (e.g., IoT edge devices) without compromising bandwidth - 8 MHz GBW at microamp quiescent current. |
| Independent dual shutdown controls | Pins 6 and 13 allow selective disabling of Ch1/Ch2 or Ch3/Ch4, enabling dynamic power scaling in multi-channel signal chains (e.g., programmable gain stages). |
| Specified for −40°C to +125°C | Qualified for industrial and automotive under-hood applications - parameters guaranteed across full temperature range, not just 25°C typical values. |

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 |
|---|---|---|---|
| TLV2784CDR | Commercial temperature range (0°C to 70°C); same electrical specs but lower cost and wider availability. | Not qualified for industrial ambient temperatures; unsuitable for outdoor or under-hood deployments. | Select TLV2784CDR only for consumer-grade products with controlled environments and cost-sensitive BOMs. |
| OPA2333PWR | Zero-drift architecture; 0.02 µV/°C offset drift vs TLV2784IDR's 8 µV/°C; higher 350 µA/channel current; 350 kHz GBW. | Better long-term DC stability for precision weighing or calibration equipment; trades bandwidth for drift performance. | Choose OPA2333PWR when offset drift dominates error budget; TLV2784IDR preferred when bandwidth/noise/power are primary constraints. |
Compared with TLV2784CDR, TLV2784IDR provides extended temperature qualification essential for industrial reliability, while OPA2333PWR sacrifices speed and power efficiency to achieve near-zero drift - making TLV2784IDR the optimal balance for wide-temperature, medium-bandwidth, low-noise analog front-ends.

FAQ
What is the maximum supply voltage for TLV2784IDR?
The absolute maximum supply voltage for TLV2784IDR is 4 V, but the recommended operating range is strictly 1.8 V to 3.6 V. Operation above 3.6 V risks parametric degradation and reduced reliability, even if within absolute ratings. TI specifies 3.6 V as the upper limit for guaranteed performance across −40°C to +125°C.
Does TLV2784IDR support true rail-to-rail output swing at 1.8 V supply?
Yes, TLV2784IDR achieves rail-to-rail output swing at 1.8 V: VOH ≥ 1.7 V and VOL ≤ 180 mV (IOL = 1 mA), meaning it drives within 100 mV of VDD and 180 mV of GND. This is validated in the Electrical Characteristics table (page 6, SLOS245E) and enables full utilization of 1.8 V ADC references.
How does the shutdown function work on TLV2784IDR?
TLV2784IDR has two independent shutdown pins: pin 6 controls channels 1 and 2; pin 13 controls channels 3 and 4. Pulling either pin <0.6 V disables the associated pair, reducing supply current to ≤1700 nA per channel. Leaving the pin floating or pulling >2 V enables the channels. Turn-on time is 800 ns; turn-off is 200 ns (RL = 2 kΩ).
Is TLV2784IDR pin-compatible with other TSSOP-14 quad op-amps?
No - TLV2784IDR uses a proprietary pinout optimized for dual shutdown control and channel grouping (Ch1/Ch2 on pins 1–3,6; Ch3/Ch4 on pins 9–11,13–14). It is not pin-compatible with generic TSSOP-14 op-amps like LM324 or TLV2464. Layout must follow the exact pin mapping shown in Figure 3 of SLOS245E.
What is the input common-mode voltage range for TLV2784IDR?
The input common-mode voltage range for TLV2784IDR is −0.2 V to VDD+0.2 V across the full −40°C to +125°C temperature range. This exceeds the supply rails, allowing direct interface to transducers biased outside the supply domain - e.g., bridge sensors with negative offset or high-side current sense configurations.
