Product details
Overview
TLV2763IDR from Texas Instruments is a dual-channel, micropower, rail-to-rail input/output operational amplifier with shutdown control, operating from 1.8 V to 3.6 V supply. It delivers 500 kHz bandwidth and 0.20 V/μs slew rate at only 20 μA per channel, with ultralow 10 nA shutdown current per channel - ideal for battery-powered sensor signal conditioning in industrial temperature range (−40°C to 85°C).
For engineers reviewing the TLV2763IDR datasheet, TLV2763IDR pinout, TLV2763IDR application, or TLV2763IDR equivalent, key selection criteria include its 1.8 V minimum supply voltage, rail-to-rail I/O capability, shutdown-enabled power gating, low input bias current (3 pA), and MSOP-8 packaging - all critical for ultra-low-power analog front-ends in portable instrumentation and IoT edge nodes.
Technical Context
The TLV2763IDR implements CMOS input stage architecture enabling rail-to-rail common-mode input range (−0.2 V to VDD + 0.2 V) and rail-to-rail output swing within 10–30 mV of rails at ±100 μA load. Its micropower design uses optimized biasing to maintain 550 μV typical input offset voltage and 95 nV/√Hz input voltage noise across 1.8–3.6 V operation.
Shutdown functionality is implemented via dedicated SHDN pin (Pin 5), asserting logic-low disables both amplifiers with <400 nA total supply current. Turn-on/turn-off times are 5 μs and 0.8 μs respectively, supporting rapid power cycling in duty-cycled measurement systems without compromising stability.

Pinout & Package
TLV2763IDR is housed in an 8-pin MSOP (DGK) package with exposed thermal pad, measuring 3.0 mm × 3.0 mm × 1.0 mm. Pin 1 is marked by a dot; pin numbering follows standard MSOP convention (counterclockwise from top-left corner).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1OUT | Channel 1 Output | Rail-to-rail capable; drives loads down to 300 kΩ while maintaining linearity |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel micropower op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2452IDR | Higher supply current (23 μA/ch), no shutdown, wider GBW (220 kHz), higher VIO (20 μV typ.) | Lacks power-gating capability; better for always-on low-noise apps where shutdown is unnecessary | Select when lower offset and higher bandwidth outweigh need for shutdown and ultra-low IQ |
| LPV821DRX | Lower supply current (650 nA/ch), no shutdown, lower GBW (10 kHz), higher VIO (250 μV typ.), same 1.8 V min supply | Optimized for nanowatt sensing; insufficient bandwidth for >1 kHz signals | Select for ultra-long-life battery apps with sub-1 kHz signal content and no active power cycling |
Compared with TLV2763IDR, TLV2452IDR trades shutdown and rail-to-rail I/O for lower offset and higher bandwidth, while LPV821DRX sacrifices speed and shutdown control to achieve 30× lower quiescent current - making TLV2763IDR the balanced choice for dual-channel, shutdown-capable, 500 kHz-capable industrial sensing.

FAQ
What is the maximum recommended supply voltage for TLV2763IDR?
The absolute maximum supply voltage for TLV2763IDR is 4 V, but the recommended operating range is strictly 1.8 V to 3.6 V per the datasheet. Operation above 3.6 V risks permanent damage and violates TI's specified reliability conditions. At 3.6 V, the device delivers optimal output swing and PSRR performance while remaining within safe thermal limits for the MSOP-8 package.
Does TLV2763IDR support true rail-to-rail input at 1.8 V supply?
Yes, TLV2763IDR supports rail-to-rail input common-mode range from −0.2 V to VDD + 0.2 V across its full operating temperature range. At 1.8 V supply, this means inputs can extend from −0.2 V to +2.0 V - enabling direct interfacing with sensors whose outputs swing below ground or beyond VDD, such as certain bridge configurations or AC-coupled sources.
How does the shutdown pin (Pin 5) behave in TLV2763IDR?
The SHDN pin on TLV2763IDR is active-low: pulling it below 0.6 V disables both amplifiers, reducing total supply current to ≤400 nA. Driving it above 2 V enables normal operation. The pin exhibits <10 pA leakage at 3.6 V, and turn-on/turn-off times are 5 μs and 0.8 μs respectively - verified under RL = 300 kΩ load per the datasheet's shutdown characteristics table.
Can TLV2763IDR drive capacitive loads directly?
TLV2763IDR is stable with ≤10 pF capacitive load at unity gain. For larger loads (e.g., ADC input capacitance >10 pF), a series null resistor (RNULL ≥20 Ω) must be placed between the output and load to preserve phase margin and prevent ringing - as confirmed in the "Driving a Capacitive Load" application note (Figure 31) of the SLOS326F datasheet.
What is the input offset voltage specification for TLV2763IDR over temperature?
TLV2763IDR has a maximum input offset voltage of 3500 μV at 25°C and 6800 μV over the full −40°C to +85°C industrial temperature range. Its typical offset drift is 9 μV/°C, meaning offset variation due to temperature is predictable and bounded - critical for DC-coupled sensor interfaces where calibration occurs at one temperature point.
