Product details
Overview
TLV7211IDBVR from Texas Instruments is a micropower CMOS comparator with rail-to-rail input, push-pull output, 15 mV max input offset voltage, 7 μA typical supply current at 5 V, and 420 ns typical propagation delay (low-to-high) at 5 V. It operates from 2.7 V to 15 V and is used in battery-powered sensor interface circuits where low quiescent current and direct capacitive load driving are critical.
For engineers reviewing the TLV7211IDBVR datasheet, TLV7211IDBVR pinout, TLV7211IDBVR application, or TLV7211IDBVR equivalent, key selection considerations include its SOT-23-5 package footprint, rail-to-rail input common-mode range beyond supply rails, internal power-on reset behavior, and absence of external pull-up requirements due to push-pull output architecture.
Technical Context
The TLV7211IDBVR implements a single-channel CMOS comparator core with internal biasing and an integrated power-on reset (POR) circuit that holds the output low for up to 200 µs during supply ramp-up or drop below 1.7 V. Its rail-to-rail input stage supports common-mode voltages from VCC– – 0.3 V to VCC+ + 0.3 V across 2.7–15 V supplies.
The push-pull output drives capacitive loads directly without external pull-up resistors, enabling fast 420 ns (tPLH) switching at 5 V with 5 mA load. Input leakage is ultra-low (0.04 pA typ), and common-mode rejection exceeds 75 dB at 5 V, supporting precision sensing in noisy portable environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 15 V - supports single-supply operation in battery-powered systems from Li-ion (3.0–4.2 V) to industrial 12 V rails. |
| Input Offset Voltage (max) | 15 mV at 25°C - defines minimum detectable differential input for threshold detection in alarm or status monitoring circuits. |
| Supply Current (typ) | 7 μA at 5 V, VOUT = Low - enables multi-year operation on coin-cell batteries in always-on sensor wake-up applications. |
| Propagation Delay (tPLH) | 420 ns at 5 V, 100 mV overdrive - ensures timely response to fast-changing analog signals such as optical interrupters or motor commutation edges. |
| Input Common-Mode Range | VCC– – 0.3 V to VCC+ + 0.3 V - allows direct interfacing to sensors operating at ground or above VCC, e.g., photodiode transimpedance outputs. |
| Output Type | Push-pull CMOS - eliminates need for external pull-up, reduces BOM count, and enables direct connection to MCU GPIO or logic inputs. |
| Operating Temperature | –40°C to +85°C - qualified for industrial and portable consumer environments including notebooks and mobile communications equipment. |
Pinout & Package
SOT-23-5 (DBV) package: 2.9 mm × 1.6 mm × 1.45 mm body, gull-wing leads, RoHS-compliant, moisture sensitivity level 1 (260°C peak reflow).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - OUT | Comparator output | CMOS push-pull driver capable of sourcing/sinking ±30 mA; compatible with 1.8–15 V logic interfaces without level-shifting. |
| 2 - VCC+ | Positive supply | Accepts 2.7–15 V; powers internal bias and output stage; must be decoupled locally with ≥0.1 μF ceramic capacitor. |
| 3 - IN+ | Non-inverting input | Rail-to-rail capable; input current < 0.04 pA enables high-impedance sensor connections (e.g., thermistors, photodiodes). |
| 4 - VCC– | Negative supply / GND | Reference node for both input and output stages; connects to system ground or negative rail in dual-supply configurations. |
| 5 - IN– | Inverting input | Rail-to-rail capable; matched to IN+ for precision differential sensing; supports hysteresis network implementation externally. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input | Enables full-supply-range signal acquisition from sensors whose output swings near VCC or GND - no level-shifting required. |
| Push-pull output | Eliminates external pull-up resistor, reducing PCB area, power loss, and signal rise-time uncertainty in high-speed threshold detection. |
| Internal power-on reset (POR) | Holds OUT low for ~200 µs during power ramp-up/down - prevents spurious logic transitions in MCU-wake or safety-critical circuits. |
| Ultra-low input current (0.04 pA) | Minimizes loading error on high-impedance sources like piezoelectric sensors or RC timing networks, preserving signal integrity. |
| 7 μA supply current (typ) | Supports >10-year battery life in coin-cell-powered IoT nodes performing periodic sensor wake-up and comparison tasks. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV7211AIDBVR | 5 mV max input offset voltage vs. 15 mV for TLV7211IDBVR; otherwise identical specs and pinout. | Preferred for precision thresholding (e.g., medical sensor zero-crossing) where sub-10 mV accuracy is mandatory. | Select TLV7211AIDBVR when tighter offset spec justifies cost premium; TLV7211IDBVR remains optimal for general-purpose battery-aware detection. |
| LMV331IDBVR | Higher 100 μA supply current, slower 200 ns min response time, no internal POR, same SOT-23-5 package. | Suitable for non-critical, higher-speed applications where POR is handled externally and battery life is secondary. | Choose LMV331IDBVR only if legacy design reuse or cost sensitivity outweighs TLV7211IDBVR's 93% lower quiescent current and built-in POR. |
Compared with TLV7211AIDBVR, TLV7211IDBVR trades 10 mV higher offset for broader availability and lower unit cost in high-volume portable designs; versus LMV331IDBVR, it delivers 14× lower supply current and guaranteed startup behavior - critical for energy-constrained edge nodes.

FAQ
What is the maximum supply voltage rating for TLV7211IDBVR?
The absolute maximum supply voltage (VCC+ – VCC–) for TLV7211IDBVR is 16 V. Operation beyond this risks permanent damage. The recommended operating range is 2.7 V to 15 V, validated across –40°C to +85°C junction temperature. At 15 V, TLV7211IDBVR maintains 15 mV max input offset and 7 μA typical supply current, making it suitable for industrial 12 V systems with margin.
Does TLV7211IDBVR require an external pull-up resistor on its output?
No, TLV7211IDBVR does not require an external pull-up resistor because it features a CMOS push-pull output stage capable of actively sourcing and sinking current. This architecture eliminates static power draw and improves rise/fall times compared to open-drain comparators. The output can directly drive logic inputs, LEDs (with series resistor), or MCU GPIO pins across its full 2.7–15 V supply range.
How does the power-on reset (POR) function in TLV7211IDBVR?
TLV7211IDBVR integrates an internal POR circuit that holds the OUT pin low for up to 200 µs after VCC+ crosses 1.7 V during power-up or drops below 1.7 V during power-down. This ensures a known, glitch-free output state during supply transients - critical for preventing false triggers in alarm circuits or uncontrolled startup in sequenced power systems using TLV7211IDBVR.
Can TLV7211IDBVR operate with a single 3.3 V supply?
Yes, TLV7211IDBVR is fully specified and functional at 3.3 V supply (within its 2.7–15 V operating range). At 3.3 V, it delivers 7 μA typical supply current, 15 mV max input offset, rail-to-rail input range (–0.3 V to +3.6 V), and 420 ns typical tPLH - making it ideal for 3.3 V microcontroller-based sensor nodes where low power and wide input dynamic range are essential.
What is the input bias current specification for TLV7211IDBVR?
The input bias current for TLV7211IDBVR is 0.04 pA typical at 25°C, with input offset current of 0.02 pA typical. This ultra-low leakage enables high-impedance sensor interfacing - for example, preserving accuracy in RC-based timing circuits or minimizing error in photodiode transimpedance amplifier feedback paths - without requiring guard traces or active guarding techniques.
