Product details
Overview
TLV7211AIDBVR from Texas Instruments is a micropower CMOS comparator with rail-to-rail input, push-pull output, 5 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 requiring low quiescent power and fast response.
For engineers reviewing the TLV7211AIDBVR datasheet, TLV7211AIDBVR pinout, TLV7211AIDBVR application, or TLV7211AIDBVR equivalent, key selection criteria include input offset voltage stability over temperature, rail-to-rail common-mode range beyond supply rails, push-pull output drive capability without external pull-up, power-on reset behavior, and SOT-23-5 package compatibility with space-constrained portable designs.
Technical Context
The TLV7211AIDBVR integrates an internal power-on reset (POR) circuit that holds the output low for up to 200 µs during supply ramp-up or ramp-down when crossing 1.7 V. Its push-pull CMOS output stage directly drives capacitive loads without external pull-up resistors, enabling clean, fast transitions across the full supply range.
It supports single-supply operation (e.g., 2.7 V to 15 V between VCC+ and VCC–) and dual-supply configurations. Input common-mode voltage extends 0.3 V beyond both supply rails (VCC– – 0.3 V to VCC+ + 0.3 V), and the device maintains 75 dB minimum CMRR and PSRR across its operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 15 V - enables direct use in 3.3 V, 5 V, and 12 V systems without level-shifting. |
| Input Offset Voltage (max) | 5 mV at 25°C - ensures accurate threshold detection in precision sensor comparators. |
| Supply Current (typ) | 7 μA at 5 V - supports multi-year battery life in always-on monitoring applications. |
| Propagation Delay (tPLH, typ) | 420 ns at 5 V, 100 mV overdrive - delivers sub-microsecond decision latency for responsive control loops. |
| Output Type | Push-pull CMOS - eliminates need for external pull-up resistor, reducing BOM count and board area. |
| Input Common-Mode Range | VCC– – 0.3 V to VCC+ + 0.3 V - allows direct interfacing with sensors operating near supply rails. |
| Power-On Reset (POR) | Holds OUT low for ≤200 µs during VCC ramp - prevents undefined logic states at startup. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV7211IDBVR | 15 mV max input offset voltage vs. 5 mV for TLV7211AIDBVR; otherwise identical specs and pinout. | Less suitable for precision thresholding (e.g., <10 mV hysteresis windows); acceptable for general-purpose voltage monitoring. | Select TLV7211IDBVR only when cost sensitivity outweighs offset-critical performance requirements. |
| LMV7219M5X/NOPB | Higher supply current (32 μA typ), faster response (120 ns), but no POR; 5-pin SOT-23 package. | Lacks power-on reset - requires external RC reset or firmware debounce; better for speed-critical, non-safety-critical apps. | Choose LMV7219M5X/NOPB only when propagation delay <200 ns is mandatory and POR is handled elsewhere in system design. |
Compared with TLV7211IDBVR and LMV7219M5X/NOPB, the TLV7211AIDBVR uniquely balances ultra-low power (7 μA), precision offset (5 mV), and integrated POR in a 5-pin SOT-23 - making it optimal for battery-powered, safety-aware, space-constrained sensing nodes where startup reliability and long service life are primary.

FAQ
What is the maximum supply voltage rating for TLV7211AIDBVR?
The TLV7211AIDBVR has an absolute maximum supply voltage (VCC+ – VCC–) of 16 V, with recommended operating range from 2.7 V to 15 V. Operation above 15 V is not specified and may compromise reliability or parametric performance per the datasheet's Absolute Maximum Ratings table.
Does TLV7211AIDBVR require an external pull-up resistor on its output?
No. The TLV7211AIDBVR features a push-pull CMOS output stage that actively drives both high and low states, eliminating the need for an external pull-up resistor. This reduces component count, PCB area, and power loss associated with passive pull-ups.
How does the power-on reset (POR) function in TLV7211AIDBVR?
The TLV7211AIDBVR incorporates 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 power-down. This ensures a defined output state before internal circuitry stabilizes, preventing erratic behavior in downstream logic.
Can TLV7211AIDBVR operate with a single 3.3 V supply?
Yes. TLV7211AIDBVR supports single-supply operation from 2.7 V to 15 V. With a 3.3 V supply (VCC+ = 3.3 V, VCC– = GND), it maintains rail-to-rail input range (–0.3 V to 3.6 V), 7 μA typical supply current, and functional push-pull output swing.
What is the input bias current specification for TLV7211AIDBVR?
The TLV7211AIDBVR exhibits an input bias current of 0.04 pA typical at 25°C, as specified in the 2.7 V, 5 V, and 15 V Electrical Characteristics tables. This ultra-low value minimizes loading errors in high-impedance sensor interfaces such as photodiode or thermopile amplifiers.
