Product details
Overview
TLV2783CDGSR from Texas Instruments is a dual 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, delivers 8 MHz gain-bandwidth, 4.8 V/µs slew rate, and 9 nV/√Hz input voltage noise at 10 kHz - enabling high-resolution data acquisition in battery-powered sensor front-ends and portable medical devices.
For engineers reviewing the TLV2783CDGSR datasheet, TLV2783CDGSR pinout, TLV2783CDGSR application, or TLV2783CDGSR equivalent, this page provides verified electrical specifications, MSOP-10 package layout, shutdown functionality details, and validated alternatives for low-voltage analog signal chain design.
Technical Context
The TLV2783CDGSR 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 for ADC driver and active filter applications.
It integrates independent shutdown control per channel (pins 5 and 12), reducing supply current to ≤1.7 µA per channel when disabled. The device features 2.5 pA typical input bias current, 50 dB minimum CMRR at 1.8 V, and 58° phase margin into 2 kΩ//25 pF loads - confirming stable unity-gain operation without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 3.6 V - supports direct operation from two alkaline or rechargeable cells; excludes ±1.8 V split-supply use beyond absolute max rating of 4 V total. |
| Gain-Bandwidth Product | 8 MHz - enables stable closed-loop gain ≥10 up to ~800 kHz; sufficient for driving 16-bit SAR ADCs with <1 LSB error at 100 kSPS. |
| Slew Rate | 4.8 V/µs (positive), 2.8 V/µs (negative) at VDD = 2.7 V - supports full-scale 1 VPP signals up to ~760 kHz without slewing distortion. |
| Input Noise Voltage | 9 nV/√Hz at 10 kHz - contributes <1.8 µV RMS noise in 100 kHz bandwidth; critical for low-noise instrumentation amplifiers. |
| Input Offset Voltage | 3000 µV max (C-grade, 0°C–70°C) - sets DC accuracy limit in precision gain stages; trimmed version TLV2783ACDGS offers 2000 µV max. |
| Shutdown Current | ≤1700 nA per channel - reduces system standby power by >99% vs active mode; enables microamp-level sleep states in portable systems. |
| Common-Mode Input Range | −0.2 V to VDD+0.2 V - accepts inputs below ground and above supply, simplifying level-shifting in mixed-signal interfaces. |
Pinout & Package
TLV2783CDGSR is housed in a 10-pin MSOP (DGK) package, 3.0 mm × 3.0 mm × 1.0 mm, with exposed thermal pad (not electrically connected). Pin 1 marked via dot; pin numbering counterclockwise from top-left corner when viewed top-down.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Buffered output of Channel 1; rail-to-rail swing capable; drives 2 kΩ load to within 180 mV of rails at 1.8 V. |
| 2 | IN−1 | Inverting input of Channel 1; 2.5 pA typical bias current; matched to IN+1 for offset minimization. |
| 3 | IN+1 | Non-inverting input of Channel 1; supports common-mode down to −0.2 V; high-impedance CMOS node. |
| 4 | GND | Analog ground reference; must be low-impedance plane; shared return for both channels and shutdown logic. |
| 5 | SHDN1 | Active-low shutdown enable for Channel 1; <0.6 V disables amp; >2 V enables; floating = enabled. |
| 6 | VDD | Positive supply; 1.8–3.6 V; requires local 0.1 µF ceramic decoupling within 0.1 inch of pin. |
| 7 | OUT2 | Buffered output of Channel 2; identical performance to OUT1; independent of Channel 1 operation. |
| 8 | IN−2 | Inverting input of Channel 2; electrically isolated from Channel 1; same bias and offset specs as IN−1. |
| 9 | IN+2 | Non-inverting input of Channel 2; supports same VICR as IN+1; no internal connection to Channel 1 inputs. |
| 10 | SHDN2 | Active-low shutdown enable for Channel 2; independent control; allows asymmetric channel enable/disable. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables full dynamic range utilization in 1.8 V systems - outputs swing within 180 mV of rails, inputs accept signals 200 mV beyond supply rails. |
| Low 650 µA/channel supply current | Permits continuous operation in energy-constrained IoT nodes; achieves 8 MHz GBW at <1.3 mW total dissipation (VDD=2.7 V). |
| Independent dual-channel shutdown | Reduces system idle power by disabling unused channel(s); SHDN1/SHDN2 pins allow staggered wake-up in multi-sensor systems. |
| 8 MHz bandwidth at 1.8 V | Maintains usable AC performance even at minimum supply - unlike many RRIO op-amps that degrade >50% GBW below 2.7 V. |
| Specified for −40°C to 125°C | Validated for automotive under-hood and industrial motor-control environments; parameters guaranteed across full temperature range. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2783IDGSR | Same die, −40°C to 125°C operating range; 3000 µV VIO max (I-grade); 55 Ω lower θJA than CDGSR. | Required for automotive or extended-temperature industrial use; not suitable for commercial-only designs due to higher cost. | Select when ambient exceeds 70°C or AEC-Q100 qualification is needed; otherwise CDGSR suffices for consumer/portable gear. |
| OPA2333AIDGSR | Zero-drift architecture; 0.02 µV/°C drift; 17 µV max VIO; 175 µA/channel; 350 kHz GBW - trades speed for ultra-low drift. | Preferred for DC-critical applications (e.g., weigh scales, precision references); unsuitable for >100 kHz signal paths. | Choose OPA2333AIDGSR only when offset drift dominates error budget; TLV2783CDGSR remains optimal for AC-coupled or bandwidth-sensitive roles. |
Compared with TLV2783IDGSR, the TLV2783CDGSR offers lower cost and adequate temp range for portable electronics, while the OPA2333AIDGSR sacrifices bandwidth to achieve sub-20 µV offset stability - making TLV2783CDGSR the balanced choice for mixed-signal data converters needing speed, noise, and supply flexibility.

FAQ
What is the maximum capacitive load the TLV2783CDGSR can drive without instability?
The TLV2783CDGSR maintains 58° phase margin into 2 kΩ//25 pF loads per the datasheet. For capacitive loads >10 pF, TI recommends adding a series null resistor (RNULL) between the output and load to preserve stability. At 100 pF, RNULL ≈ 20 Ω restores clean step response; layout parasitics must also be minimized near the output pin. TLV2783CDGSR does not integrate isolation resistance, so external compensation is required for heavy capacitive loading.
Does the TLV2783CDGSR support true single-supply operation with input signals below ground?
Yes - the TLV2783CDGSR's input common-mode range extends to −0.2 V (200 mV below GND), enabling acceptance of slightly negative signals in single-supply configurations. This eliminates need for level-shifting circuitry in applications like electrophysiology front-ends or bipolar sensor interfaces. However, inputs must not exceed −0.3 V to avoid damage, and output cannot swing below GND.
How does shutdown affect output state in the TLV2783CDGSR?
When either SHDN1 or SHDN2 is pulled low, the corresponding amplifier channel disables and its output enters high-impedance (Hi-Z) state - not tri-state in the digital sense, but effectively disconnected from the load. Outputs do not clamp or short; they float. This allows safe multiplexing of multiple TLV2783CDGSR outputs onto a shared bus or ADC input without contention, provided external pull-up/down resistors define idle voltage.
Can the TLV2783CDGSR be used with a 3.3 V supply despite its 3.6 V max rating?
Yes - the TLV2783CDGSR is fully specified at 3.3 V (within its 1.8 V–3.6 V range). At 3.3 V, it delivers 4.2 V/µs negative slew rate, 3.55 V high-level output voltage at 5 mA sink, and 8 MHz GBW. All parameters in the datasheet include 3.3 V test conditions, and thermal dissipation remains within limits (θJA = 259.9°C/W for DGK package). No derating is required.
What is the typical input bias current mismatch between channels in the TLV2783CDGSR?
The TLV2783CDGSR exhibits matched input bias currents between channels, with typical IIB = 2.5 pA per input and maximum IIO = 100 pA (full range). This 40:1 matching ratio ensures minimal offset voltage contribution from resistor networks - critical in dual-op-amp configurations like difference amplifiers or dual-supply virtual-ground generators where channel-to-channel tracking matters.
