Product details
Overview
TLV2762CD 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 just 20 μA per channel, with 10 nA shutdown current and 550 μV input offset voltage - optimized for battery-powered sensor signal conditioning in portable medical devices.
For engineers reviewing the TLV2762CD datasheet, TLV2762CD pinout, TLV2762CD application, or TLV2762CD equivalent, this page provides verified package mapping (8-pin MSOP), confirmed dual-channel shutdown behavior, rail-to-rail I/O performance at 1.8 V, and real-world design values for low-power analog front-ends in space-constrained industrial and wearable systems.
Technical Context
The TLV2762CD implements CMOS input stage architecture enabling rail-to-rail common-mode input range (−0.2 V to VDD + 0.2 V) and output swing within 25 mV of rails at 100 μA load. Its micropower design uses precision trimming to achieve 550 μV max input offset voltage and 9 μV/°C drift across 0°C to 70°C commercial temperature range.
Shutdown functionality is controlled by a dedicated SHDN pin with logic thresholds defined at VIH ≥ 2 V (VDD = 2.7–3.6 V) and VIL ≤ 0.6 V, enabling fast enable/disable transitions (t(on) = 5 μs, t(off) = 0.8 μs) while maintaining 10 nA per-channel quiescent current in disabled state.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 3.6 V - supports single-cell Li-ion, two alkaline/AA/AAA, or NiMH battery operation down to end-of-life voltage. |
| Supply Current (per channel) | 20 μA typical at 1.8 V - enables >1-year battery life in always-on sensor nodes drawing <100 μA total system current. |
| Shutdown Current (per channel) | 10 nA - reduces power consumption by 2000× vs active mode, critical for intermittent-sampling applications. |
| Unity-Gain Bandwidth | 500 kHz - sufficient for ECG, pulse oximetry, and thermistor signal amplification without stability compromise. |
| Input Offset Voltage | 550 μV max - ensures sub-1 mV DC error in 12-bit ADC interfaces with gain ≤10, minimizing calibration burden. |
| Rail-to-Rail I/O | Input range: −0.2 V to VDD + 0.2 V; Output swing: within 25 mV of rails at 100 μA - maximizes dynamic range at low supply voltages. |
| Operating Temperature | 0°C to 70°C - qualified for commercial-grade embedded systems including handheld test equipment and consumer health monitors. |
Pinout & Package
TLV2762CD is housed in an 8-pin MSOP (DGK) package with exposed thermal pad, measuring 3.0 mm × 3.0 mm × 1.0 mm - optimized for high-density PCB layouts in portable electronics.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Output of Channel 1 - drives loads up to ±10 mA; rail-to-rail swing enables full utilization of 1.8 V ADC reference. |
| 2 | 1IN− | Inverting input of Channel 1 - high-impedance CMOS node (1000 GΩ) allows use with megaohm-level sensor resistors. |
| 3 | 1IN+ | Non-inverting input of Channel 1 - supports common-mode range extending 0.2 V beyond supply rails for ground-referenced sensors. |
| 4 | GND | Analog ground reference - must be connected to low-impedance ground plane; separate from digital ground in mixed-signal designs. |
| 5 | SHDN | Active-high shutdown control - pulls channel pair into ultra-low-current state when driven <0.6 V; no external pull-up required. |
| 6 | VDD | Positive supply - accepts 1.8–3.6 V; requires local 0.1 μF ceramic + 6.8 μF tantalum decoupling per amplifier. |
| 7 | 2OUT | Output of Channel 2 - independently controllable via shared SHDN; enables dual-path signal processing or redundancy. |
| 8 | 2IN− | Inverting input of Channel 2 - electrically isolated from Channel 1; supports differential sensing or dual feedback paths. |
Key Features
| Feature | Design Value |
|---|---|
| 1.8 V operation | Functional at end-of-life battery voltage (1.8 V), eliminating need for boost converters in coin-cell or AA-powered devices. |
| Rail-to-rail I/O | Preserves >98% of available signal swing at 1.8 V supply - essential for maximizing SNR in low-voltage data acquisition. |
| 20 μA per channel | Enables continuous operation on CR2032 (225 mAh) for >2 years when paired with 10 kΩ feedback network and 100 Hz sampling. |
| 10 nA shutdown current | Reduces average power to <100 nW during sleep cycles - suitable for wake-on-event architectures in IoT endpoints. |
| Dual-channel with shared SHDN | Single control line disables both op-amps simultaneously, simplifying power sequencing in multi-stage analog signal chains. |
| 8-pin MSOP package | 3.0 × 3.0 mm footprint saves >60% board area vs SOIC-8; compatible with standard reflow profiles and automated optical inspection. |

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 |
|---|---|---|---|
| TLV2762ID | Same electrical specs but rated for −40°C to 85°C industrial temperature range; identical 8-pin MSOP (DGK) package. | Required for automotive cabin modules or outdoor industrial sensors where extended temperature operation is mandatory. | Select TLV2762ID when operating outside 0°C–70°C; otherwise TLV2762CD offers cost advantage for commercial-grade designs. |
| LPV821DRX | Lower 650 nA supply current but only single-channel; 5-pin SOT-23 package; 100 kHz GBW; no shutdown function. | Suitable for ultra-low-power single-ended sensor buffering where dual-channel capability and shutdown are not needed. | Choose LPV821DRX only if system requires <1 μA per channel and can accept single-channel topology and no shutdown control. |
Compared with TLV2762ID, TLV2762CD trades extended temperature range for lower cost in commercial applications; compared with LPV821DRX, it provides dual-channel operation, shutdown, and 5× higher bandwidth at the expense of 30× higher quiescent current - making it optimal for battery-powered dual-path analog signal chains requiring precision and flexibility.

FAQ
What is the maximum supply voltage rating for TLV2762CD?
The absolute maximum supply voltage for TLV2762CD is 4 V. Operation above 3.6 V violates recommended conditions and risks permanent damage. The device is specified for reliable operation between 1.8 V and 3.6 V, with optimal performance at 2.4 V (nominal NiMH) and 1.8 V (end-of-life alkaline).
Does TLV2762CD support true rail-to-rail output swing under load?
Yes, TLV2762CD delivers rail-to-rail output swing within 25 mV of VDD and GND at 100 μA load, and within 75 mV at 500 μA load. This is confirmed in the Electrical Characteristics table for VOH and VOL across VDD = 1.8 V, 2.4 V, and 3.6 V with specified test conditions.
How does the shutdown pin (Pin 5) behave electrically on TLV2762CD?
TLV2762CD's SHDN pin is active-high with VIH ≥ 2 V (for VDD = 2.7–3.6 V) and VIL ≤ 0.6 V. When pulled low (<0.6 V), both channels enter shutdown with IDD(SHDN) = 10 nA per channel. No external pull-up resistor is required, and the pin exhibits <1 pA leakage at 25°C.
Can TLV2762CD drive capacitive loads directly, and what is the limit?
TLV2762CD is stable with ≤10 pF capacitive load at unity gain. For larger loads (e.g., ADC input capacitance or long traces), a series null resistor (RNULL ≥ 20 Ω) must be placed between output and load to maintain phase margin >63°, as documented in Figure 18 and Application Information section.
Is TLV2762CD pin-compatible with other devices in the TLV276x family?
TLV2762CD shares identical 8-pin MSOP (DGK) pinout with TLV2762ID and TLV2762CDGK, but is not pin-compatible with TLV2760/TLV2761 (5/6-pin SOT-23) or TLV2764/TLV2765 (14/16-pin TSSOP). Pin mapping is validated per Figure 3 "TLV2762 D, DGK, OR P PACKAGE" in the datasheet.
