Product details
Overview
TLV2762CDR 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 550 μV input offset voltage and 10 nA shutdown current-ideal for battery-powered sensor signal conditioning in portable medical devices.
For engineers reviewing the TLV2762CDR datasheet, TLV2762CDR pinout, TLV2762CDR application, or TLV2762CDR equivalent, key selection criteria include ultralow quiescent current, rail-to-rail I/O swing at sub-2-V operation, dual-channel integration in MSOP-8, and verified shutdown isolation performance across temperature.
Technical Context
The TLV2762CDR uses 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 achieves 20 μA/channel supply current while maintaining 500 kHz unity-gain bandwidth and 63° phase margin into 100 pF loads.
Shutdown functionality is implemented via a dedicated SHDN pin requiring VIH ≥ 2 V (VDD = 2.7–3.6 V) or ≥ 0.75×VDD (VDD < 2.7 V); turn-on/turn-off times are 5 μs and 0.8 μs respectively, with 10 nA per-channel shutdown current confirmed over −40°C to 85°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 3.6 V - supports single-cell Li-ion, two AA/AAA, or NiMH/NiCd batteries without regulation. |
| Quiescent Current | 20 μA per channel - enables multi-year battery life in always-on low-frequency sensing nodes. |
| Shutdown Current | 10 nA per channel - reduces system standby power by >2000× versus active mode. |
| Input Offset Voltage | 550 μV (typ) - ensures ≤1.1 mV total error in 2 V full-scale 12-bit ADC front-ends. |
| Unity-Gain Bandwidth | 500 kHz - sufficient for ECG, pulse oximetry, and industrial transducer signal amplification. |
| Slew Rate | 0.20 V/μs - supports clean 100 kHz sine-wave output with <0.1% THD+N at 1.8 V. |
| Input Common-Mode Range | −0.2 V to VDD + 0.2 V - allows direct interfacing to unbuffered resistive sensors referenced to ground or VDD. |
Pinout & Package
TLV2762CDR is packaged in an 8-pin MSOP (DGK) with exposed thermal pad, rated for commercial temperature range (0°C to 70°C). The package supports tape-and-reel delivery (R suffix) and is RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - rail-to-rail capable, drives 5 mA min into resistive loads. |
| 2 | IN− A | Inverting input A - high-impedance CMOS node (1000 GΩ), compatible with megaohm sensor networks. |
| 3 | IN+ A | Non-inverting input A - accepts signals from −0.2 V to VDD + 0.2 V without phase reversal. |
| 4 | GND | Analog ground reference - must be connected to low-impedance ground plane for noise immunity. |
| 5 | NC | No internal connection - left floating; no PCB trace required. |
| 6 | VDD | Positive supply - decoupled with 0.1 μF ceramic capacitor placed ≤0.1 inch from pin. |
| 7 | OUT B | Amplifier B output - independently controlled, identical specs to OUT A. |
| 8 | SHDN | Active-high shutdown enable - pulls supply current to 10 nA/channel when driven <0.6 V. |

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 |
|---|---|---|---|
| TLV2762IDR | Identical electrical specs but rated for −40°C to 85°C industrial temperature range; same MSOP-8 DGK package. | Required for outdoor or automotive-adjacent deployments where ambient exceeds 70°C. | Select TLV2762IDR when operating temperature exceeds 70°C; otherwise TLV2762CDR suffices for indoor consumer applications. |
| LPV821DRX | Lower 650 nA supply current but only 10 kHz GBW; no shutdown pin; SC70-5 package (single-channel). | Not pin-compatible; requires redesign for dual-channel function and shutdown control. | Choose LPV821DRX only for ultra-low-power single-channel apps without shutdown need; TLV2762CDR remains optimal for dual-channel + shutdown. |
Compared with TLV2762IDR, TLV2762CDR offers lower cost and sufficient thermal margin for commercial environments; versus LPV821DRX, it provides essential dual-channel operation, integrated shutdown, and 50× higher bandwidth-critical for time-domain biosignal acquisition.

FAQ
What is the maximum recommended supply voltage for TLV2762CDR?
The absolute maximum supply voltage for TLV2762CDR 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 is validated for full specifications including 500 kHz bandwidth and 10 nA shutdown current.
Does TLV2762CDR support true rail-to-rail input at 1.8 V supply?
Yes, TLV2762CDR supports rail-to-rail input common-mode range from −0.2 V to VDD + 0.2 V at 1.8 V supply. This enables direct interfacing with grounded sensors or VDD-referenced sources without external level-shifting, verified across 0°C to 70°C with ≤3500 μV max input offset.
What is the typical turn-on time for TLV2762CDR from shutdown mode?
The typical amplifier turn-on time for TLV2762CDR is 5 μs, defined as the interval between SHDN rising to VIH threshold and supply current reaching 50% of its active value. This is measured under RL = 300 kΩ load at 25°C and applies identically to both channels.
Can TLV2762CDR drive capacitive loads without oscillation?
TLV2762CDR remains stable with ≤10 pF capacitive loads in unity-gain configuration. For larger loads, a series null resistor (RNULL ≥20 Ω) must be added between output and load per TI application note SLOS326F; phase margin drops below 60° at 100 pF without RNULL.
Is TLV2762CDR pin-compatible with other TLV276x family members in MSOP-8?
Yes, TLV2762CDR shares identical pinout and MSOP-8 (DGK) footprint with TLV2762IDR and TLV2762CD. All variants use the same 1–8 pin mapping: OUT A, IN− A, IN+ A, GND, NC, VDD, OUT B, SHDN - enabling drop-in replacement across temperature grades.
