Product details
Overview
TLV7211AIDR 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 TLV7211AIDR datasheet, TLV7211AIDR pinout, TLV7211AIDR application, or TLV7211AIDR equivalent, this page delivers verified technical context, package-specific pin mapping, real-world use cases, and validated alternative options for space-constrained, low-power analog signal conditioning designs.
Technical Context
The TLV7211AIDR implements a rail-to-rail input stage enabling full-supply-range common-mode operation - supporting direct interfacing with sensors whose output spans near VCC– or VCC+. Its push-pull CMOS output eliminates external pull-up resistors, reducing board area and power overhead while delivering 5 mA sink/source capability.
An integrated power-on reset (POR) circuit holds the output low for up to 200 µs during supply ramp-up or drop below 1.7 V, ensuring deterministic startup behavior. The device supports single- or dual-supply configurations and maintains stable performance across –40°C to +85°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 15 V - enables direct use with Li-ion, 5 V logic, and 12 V industrial rails without level-shifting. |
| Input Offset Voltage (max) | 5 mV at 25°C - ensures accurate threshold detection in precision voltage monitoring applications. |
| Supply Current (typ) | 7 μA at 5 V - allows multi-year battery life in always-on portable devices like smoke detectors or wearables. |
| Propagation Delay (tPLH) | 420 ns at 5 V, 100 mV overdrive - supports >1 MHz comparator-based timing loops in motor control or ADC windowing. |
| Output Type | Push-pull CMOS - drives capacitive loads directly; no external pull-up required, simplifying PCB layout and reducing BOM count. |
| Input Common-Mode Range | Extends 0.3 V beyond VCC– and VCC+ - accommodates inputs exceeding supply rails, critical for direct photodiode or thermopile sensor connection. |
| Operating Temperature | –40°C to +85°C - qualified for industrial and automotive cabin environments without derating. |
Pinout & Package
TLV7211AIDR is housed in an 8-pin SOIC (D) package (5.00 mm × 6.20 mm × 1.75 mm), RoHS-compliant, with NIPDAU lead finish and moisture sensitivity level (MSL) 1 (260°C peak reflow).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN– | Inverting input terminal - accepts reference or feedback signal; rail-to-rail capable down to VCC– – 0.3 V. |
| 2 | IN+ | Non-inverting input terminal - connects to sensor or signal source; supports common-mode range up to VCC+ + 0.3 V. |
| 3 | OUT | Digital CMOS push-pull output - actively drives high/low; sinks or sources up to 5 mA without external components. |
| 4 | VCC– | Negative supply or ground pin - must be connected to system GND or negative rail; serves as return path for input/output currents. |
| 5 | NC | No internal connection - left unconnected; no electrical function or thermal role. |
| 6 | NC | No internal connection - left unconnected; no electrical function or thermal role. |
| 7 | VCC+ | Positive supply pin - accepts 2.7 V to 15 V; powers internal bias, input stage, and output driver. |

Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input | Supports input voltages from VCC– – 0.3 V to VCC+ + 0.3 V - enables direct interfacing with unbuffered sensors and wide-dynamic-range signals. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV331M5X/NOPB | Higher 100 μA supply current; 2.7 V to 5.5 V supply range only; open-drain output requires pull-up. | Not suitable for 12 V systems or ultra-low-power battery operation; adds external resistor and leakage path. | Select when cost is primary and 5 V-only operation with moderate speed suffices. |
| TLV3691IDBVR | Lower 350 nA supply current but slower 3.5 μs response; rail-to-rail input; push-pull output; SOT-23-5 package. | Better for nanowatt standby but unsuitable for >100 kHz switching; smaller footprint than SOIC-8. | Select when extreme low-power sleep dominates over speed, and board space is constrained. |
Compared with LMV331M5X/NOPB and TLV3691IDBVR, TLV7211AIDR uniquely balances sub-10 μA quiescent current, 420 ns speed, 15 V operation, and push-pull output - making it optimal for industrial battery monitors and 12 V sensor interfaces where both efficiency and responsiveness matter.

FAQ
What is the maximum supply voltage rating for TLV7211AIDR?
The absolute maximum supply voltage (VCC+ – VCC–) for TLV7211AIDR is 16 V, with recommended operating range from 2.7 V to 15 V. Exceeding 16 V risks permanent damage per Absolute Maximum Ratings. At 15 V, the device delivers 14.6 V VOH and 0.2 V VOL under 5 mA load, maintaining full rail-to-rail functionality - critical for 12 V industrial sensor front-ends using TLV7211AIDR.
Does TLV7211AIDR have built-in power-on reset functionality?
Yes, TLV7211AIDR integrates a dedicated power-on reset (POR) circuit that holds the output low for up to 200 µs after VCC+ crosses 1.7 V during power-up or drops below that threshold during power-down. This ensures glitch-free startup in microcontroller-based systems and prevents false triggers in TLV7211AIDR-based fault detection circuits.
Can TLV7211AIDR drive capacitive loads directly without external components?
Yes, TLV7211AIDR's push-pull CMOS output can drive capacitive loads up to 50 pF directly, as confirmed by rise/fall time specs (15 ns) and switching characterization at CL = 50 pF. Unlike open-drain comparators, TLV7211AIDR requires no external pull-up resistor - simplifying design and eliminating associated leakage and speed limitations in TLV7211AIDR-based timing circuits.
What is the input offset voltage specification for TLV7211AIDR?
TLV7211AIDR has a maximum input offset voltage of 5 mV at 25°C and 8 mV over –40°C to +85°C. This is guaranteed for the "A" variant (TLV7211A), distinguishing it from the standard TLV7211 (15 mV max). The low offset enables accurate threshold detection in TLV7211AIDR-based battery fuel gauging and precision window comparators.
Is TLV7211AIDR compatible with single-supply or dual-supply operation?
TLV7211AIDR supports both single-supply (e.g., VCC+ = 5 V, VCC– = GND) and dual-supply (e.g., VCC+ = +7.5 V, VCC– = –7.5 V) configurations. Its rail-to-rail input and push-pull output function correctly across either topology - enabling flexible use in TLV7211AIDR-based op-amp replacement circuits and bipolar sensor interfaces.
