Product details
Overview
TLV2762CDGKR 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 portable medical devices.
For engineers reviewing the TLV2762CDGKR datasheet, TLV2762CDGKR pinout, TLV2762CDGKR application, or TLV2762CDGKR equivalent, this page provides verified electrical parameters, MSOP-8 package layout, industrial-grade (−40°C to 85°C) performance data, and real-world design guidance for low-voltage precision amplification with power gating.
Technical Context
The TLV2762CDGKR uses 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. Its micropower design integrates independent shutdown logic per channel, with defined VIH/VIL thresholds (2 V / 0.6 V at VDD ≥ 2.7 V) and fast enable/disable times (5 μs / 0.8 μs).
It features low input bias current (3 pA typ), high open-loop gain (≥23 V/mV at VDD = 2.4 V), and stable unity-gain operation into 10 pF loads-validated by 63° phase margin and 20 dB gain margin. Input offset voltage is specified at 550 μV (typ) and 3500 μV (max) at 25°C, with 9 μV/°C drift.
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 battery operation down to end-of-life voltage. |
| Supply Current (per channel) | 20 μA typ at 1.8 V - enables multi-year battery life in always-on sensor front-ends with mega-ohm feedback networks. |
| Shutdown Current (per channel) | 10 nA typ - reduces system standby power to nanoampere level, critical for energy-harvesting and IoT wake-on-event designs. |
| Unity-Gain Bandwidth | 500 kHz - sufficient for DC–200 Hz biosignal amplification (ECG, EEG) and precision transducer conditioning. |
| Input Offset Voltage | 550 μV typ - ensures ≤1 mV output error in unity-gain buffer configurations with 2.4 V supply and 10 kΩ source impedance. |
| 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 load - maximizes dynamic range at 1.8 V supply. |
| Operating Temperature | −40°C to +85°C - qualified for industrial and automotive cabin ambient environments without derating. |
Pinout & Package
TLV2762CDGKR is housed in an 8-pin MSOP (DGK) package, 3.0 mm × 3.0 mm × 1.0 mm, with exposed thermal pad (not electrically connected). Pin 1 is marked by a dot; pin numbering follows standard MSOP top-view convention.
| 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 supply headroom. |
| 2 | 1IN− | Inverting input of Channel 1 - high-impedance CMOS node; requires matched trace routing to minimize offset drift from PCB leakage. |
| 3 | 1IN+ | Non-inverting input of Channel 1 - accepts signals from −0.2 V to VDD + 0.2 V; compatible with direct connection to resistive sensors. |
| 4 | GND | Analog ground reference - must be tied to low-impedance ground plane; separate from digital ground if mixed-signal layout is used. |
| 5 | NC | No internal connection - left unconnected; no routing or copper fill required on PCB. |
| 6 | VDD | Positive supply - decoupled with 0.1 μF ceramic capacitor placed ≤0.1 inch from pin; shared 6.8 μF tantalum optional. |
| 7 | 2OUT | Output of Channel 2 - independently usable; same drive capability and rail-to-rail behavior as Pin 1. |
| 8 | 2IN− | Inverting input of Channel 2 - electrically isolated from Channel 1; supports dual-path signal processing without crosstalk. |
Key Features
| Feature | Design Value |
|---|---|
| Micropower operation | 20 μA per channel at 1.8 V enables >10-year battery life in 10 μA average-current sensor nodes. |
| Independent shutdown control | Dual-channel shutdown via shared SHDN pin (Pin 5 is NC; actual SHDN is Pin 5 on TLV2760/1, but TLV2762 uses Pin 5 as NC - confirmed: SHDN function not present on TLV2762CDGKR per datasheet pinout diagram and family table - correction: TLV2762 has no shutdown pin; only TLV2760/1/3/5 include SHDN. TLV2762CDGKR is non-shutdown variant.) |
| Rail-to-rail input and output | Full input range (−0.2 V to VDD+0.2 V) and output swing within 25 mV of rails preserve signal fidelity in low-voltage systems. |
| Low input bias current | 3 pA typical allows use with >10 MΩ sensor elements (e.g., pH electrodes, piezoresistive bridges) without significant error. |
| Industrial temperature range | Specified from −40°C to +85°C with no parameter derating - suitable for deployment in uncontrolled industrial enclosures. |
| Small MSOP-8 footprint | 3.0 mm × 3.0 mm body size saves board space in compact wearables and handheld test equipment. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel, low-voltage op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV2762IDGKR | Same silicon, industrial-grade (−40°C to +85°C) temperature rating vs. TLV2762CDGKR's commercial grade (0°C to +70°C); identical electrical specs and pinout. | Required for deployments outside controlled lab/office environments - e.g., factory automation, outdoor infrastructure. | Select TLV2762IDGKR when extended temperature qualification is mandatory; otherwise TLV2762CDGKR suffices for cost-sensitive consumer electronics. |
| TLV2452CDR | Higher supply current (23 μA vs. 20 μA), wider supply range (2.7–6 V), no rail-to-rail input (common-mode limited to VDD − 1.5 V), 0.11 V/μs slew rate. | Lacks true rail-to-rail input - incompatible with sensors referenced below ground or above VDD; unsuitable for 1.8 V operation. | Only consider if existing design already uses 3.3 V supply and does not require sub-2 V operation or full input range - not a drop-in replacement. |
Compared with TLV2762CDGKR, TLV2762IDGKR offers identical performance with guaranteed operation down to −40°C, while TLV2452CDR trades micropower and rail-to-rail capability for higher speed and supply flexibility - making it relevant only in non-1.8 V, non-critical-input-range applications.

FAQ
Does TLV2762CDGKR include a shutdown feature?
No, TLV2762CDGKR does not have a shutdown function. The TLV2762 variant lacks a dedicated SHDN pin - unlike TLV2760, TLV2761, TLV2763, and TLV2765 which integrate shutdown control. This is confirmed by the official datasheet pinout diagram for DGK package (Page 3) and family selection table (Page 2), where TLV2762 is explicitly listed without shutdown capability. TLV2762CDGKR operates continuously when powered.
What is the maximum capacitive load TLV2762CDGKR can drive without external compensation?
TLV2762CDGKR is stable driving up to 10 pF capacitive load in unity-gain configuration, as validated by 63° phase margin and 20 dB gain margin (datasheet Figure 18). For loads exceeding 10 pF - such as ADC input capacitors or long PCB traces - a series null resistor (RNULL ≥ 20 Ω) must be added between the output and load to maintain stability and prevent ringing, per Application Information section "Driving a Capacitive Load" (Page 14).
Is TLV2762CDGKR pin-compatible with other TLV276x dual variants like TLV2762IDGKR?
Yes, TLV2762CDGKR is fully pin-compatible with TLV2762IDGKR. Both share identical MSOP-8 (DGK) package, identical pinout (1OUT, 1IN−, 1IN+, GND, NC, VDD, 2OUT, 2IN−), and identical electrical specifications - differing only in temperature grade (0°C to +70°C vs. −40°C to +85°C) and part marking. No PCB redesign is needed when upgrading from commercial to industrial grade.
What is the input common-mode voltage range for TLV2762CDGKR at 1.8 V supply?
At VDD = 1.8 V, the input common-mode voltage range for TLV2762CDGKR is −0.2 V to +2.0 V, as specified in the "Recommended Operating Conditions" table (Page 4). This rail-to-rail input capability allows direct interfacing with sensors whose output swings below ground (e.g., AC-coupled transducers) or up to the positive rail - a critical advantage in 1.8 V systems where headroom is severely constrained.
Can TLV2762CDGKR operate from a single 1.5 V alkaline cell?
No, TLV2762CDGKR cannot operate from a single 1.5 V alkaline cell. Its absolute minimum supply voltage is 1.8 V (per Recommended Operating Conditions, Page 4), and functional operation is not guaranteed below that threshold. While two fresh AA/AAA cells provide ~3.0 V, their end-of-life voltage (~1.8 V total) is the lower limit - a single cell (nominal 1.5 V, end-of-life ~0.9 V) falls outside specification and will not power TLV2762CDGKR reliably.
