Product details
Overview
TLV2782CDR from Texas Instruments is a dual 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 bandwidth and 4.8 V/µs slew rate at just 650 µA per channel, and supports −0.2 V to VDD+0.2 V common-mode input range - ideal for precision signal conditioning in battery-powered sensor interfaces and portable data acquisition systems.
For engineers reviewing the TLV2782CDR datasheet, TLV2782CDR pinout, TLV2782CDR application, or TLV2782CDR equivalent, key selection criteria include its dual-channel SOIC-8 package, shutdown capability (enabled on TLV2783/2785 only), guaranteed 3000 µV max input offset voltage over 0°C to 70°C, and compatibility with single-cell Li-ion or two-cell NiMH supplies.
Technical Context
The TLV2782CDR implements a CMOS input stage enabling picoampere-level input bias current (2.5 pA typ) and rail-to-rail input swing exceeding supply rails by ±0.2 V. Its unity-gain-stable architecture achieves 8 MHz gain-bandwidth product with 58° phase margin into 2 kΩ//25 pF loads, supporting high-fidelity amplification of fast analog signals without external compensation.
Unlike members with shutdown (e.g., TLV2783), the TLV2782CDR lacks a dedicated SHDN pin - confirmed by its D-package pinout showing pins 1–8 as OUT1, IN−1, IN+1, GND, VDD, OUT2, IN−2, IN+2 - making it suitable for always-on, low-noise dual-amplifier configurations where power sequencing is managed externally.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 3.6 V - enables direct operation from single Li-ion (3.0–3.6 V) or two alkaline/NiMH cells (2.4–3.0 V) without regulation. |
| Bandwidth (GBW) | 8 MHz - supports accurate amplification of signals up to ~1 MHz in closed-loop gain ≥8 configurations. |
| Slew Rate | 4.8 V/µs at VDD = 2.7 V - ensures <2.8 µs settling to 0.1% for 1 VPP step inputs, critical for ADC driver stages. |
| Input Offset Voltage | 3000 µV max (0°C to 70°C) - defines worst-case DC error in precision gain stages; 250 µV typ enables sub-mV accuracy with calibration. |
| Supply Current | 650 µA per channel - draws only 1.3 mA total for dual-channel operation, extending battery life in portable instrumentation. |
| Input Noise Voltage | 9 nV/√Hz at 10 kHz - low enough for 16-bit SAR ADC front-ends with ≤100 kHz signal bandwidth. |
| Rail-to-Rail I/O | Input range: −0.2 V to VDD+0.2 V; Output swing: within 180 mV of rails at 1 mA - maximizes dynamic range in low-voltage systems. |
Pinout & Package
TLV2782CDR is supplied in an 8-pin SOIC (D) package, tape-and-reel format (R suffix). The package measures 4.90 mm × 3.91 mm × 1.75 mm and is RoHS-compliant.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Amplifier 1 output - drives loads up to ±10 mA; rail-to-rail swing enables full utilization of ADC input range. |
| 2 | IN−1 | Inverting input of Amp 1 - high-impedance CMOS node; requires matched trace lengths to minimize noise pickup. |
| 3 | IN+1 | Non-inverting input of Amp 1 - accepts signals from −0.2 V to VDD+0.2 V, enabling level-shifting and single-supply transducer interfacing. |
| 4 | GND | Analog ground reference - must connect to low-impedance ground plane; separates signal return from power return in mixed-signal PCBs. |
| 5 | VDD | Positive supply - accepts 1.8–3.6 V; requires local 0.1 µF ceramic + 6.8 µF tantalum decoupling per amplifier pair. |
| 6 | OUT2 | Amplifier 2 output - independent channel; allows dual-path signal processing (e.g., differential drive or active filtering). |
| 7 | IN−2 | Inverting input of Amp 2 - electrically isolated from Amp 1; supports independent feedback networks without crosstalk. |
| 8 | IN+2 | Non-inverting input of Amp 2 - identical input specification to Pin 3; enables matched dual-channel sensor signal conditioning. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full-scale signal handling from 0 V to VDD without clipping - essential for maximizing SNR in 1.8 V–3.3 V microcontroller-based systems. |
| Low 650 µA/channel supply current | Reduces total quiescent power to 2.34 mW at 3.6 V - suitable for always-on monitoring nodes in IoT edge devices. |
| 8 MHz gain-bandwidth product | Supports closed-loop gains up to 80 with >100 kHz small-signal bandwidth - sufficient for anti-aliasing filters and active sensor excitation. |
| 9 nV/√Hz input voltage noise | Minimizes added noise in high-gain, low-frequency sensor amplifiers (e.g., thermopile or strain gauge bridges) operating below 100 kHz. |
| CMOS input stage (2.5 pA IIB) | Eliminates bias current errors in high-impedance source applications (e.g., pH electrodes or photodiode transimpedance amps). |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2782IDR | Same electrical specs but rated for −40°C to 125°C industrial temperature range; 3000 µV VIO max over full range vs. C-grade's 0°C–70°C spec. | Required for under-hood automotive or factory-floor industrial control where ambient exceeds 70°C. | Select TLV2782IDR when extended temperature operation is mandatory; otherwise TLV2782CDR offers cost advantage for commercial-grade designs. |
| OPA2333AIDR | Zero-drift architecture (0.02 µV/°C drift), lower 17 µV max VIO, higher 350 kHz GBW, but 17 µA/channel supply current - 26× higher than TLV2782CDR. | Used where long-term DC stability dominates over power consumption - e.g., precision weight scales or medical diagnostic equipment. | Choose OPA2333AIDR only when µV-level offset drift matters more than battery life; TLV2782CDR remains optimal for portable, cost-sensitive, wide-bandwidth apps. |
Compared with TLV2782IDR, TLV2782CDR trades extended temperature rating for lower cost and identical performance at room temperature; versus OPA2333AIDR, it sacrifices ultra-low drift and precision for 26× lower quiescent current and 23× higher bandwidth - making TLV2782CDR the preferred choice for power-constrained, medium-accuracy signal chains.

FAQ
What is the maximum supply voltage for TLV2782CDR?
The absolute maximum supply voltage for TLV2782CDR 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; operation at 3.6 V delivers optimal slew rate (5 V/µs) and output drive capability while maintaining 650 µA/channel supply current.
Does TLV2782CDR have a shutdown pin?
No, TLV2782CDR does not include a shutdown function. Shutdown capability is only present on TLV2780, TLV2783, and TLV2785 variants - confirmed by the absence of SHDN pins in the TLV2782 D-package pinout (pins 1–8 are OUT1, IN−1, IN+1, GND, VDD, OUT2, IN−2, IN+2). Power management must be handled externally.
What is the input offset voltage specification for TLV2782CDR?
TLV2782CDR has a maximum input offset voltage of 3000 µV over the commercial temperature range (0°C to 70°C), with a typical value of 250 µV at 25°C. This specification is guaranteed per the datasheet's "TLV2782CD" ordering option table and applies to the C-suffix grade used in TLV2782CDR.
Which package type is used for TLV2782CDR?
TLV2782CDR uses the 8-pin SOIC (D) package, supplied in tape-and-reel format - indicated by the "R" suffix in the part number. The SOIC-8 footprint (4.90 mm × 3.91 mm) is industry-standard, compatible with automated SMT assembly, and provides adequate thermal dissipation (θJA = 176°C/W) for ≤1.3 mA total supply current.
Can TLV2782CDR drive capacitive loads directly?
TLV2782CDR can drive ≤10 pF capacitive loads stably; for larger loads (e.g., ADC input capacitance or long cables), a series resistor (RNULL) of 10–50 Ω must be placed between the output and load to maintain ≥58° phase margin and prevent ringing - as specified in the "Driving a Capacitive Load" application note (Figure 30) of the TLV278x datasheet.
