Product details
Overview
TLV7211AID 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 - deployed in battery-powered sensor interface and portable electronics systems.
For engineers reviewing the TLV7211AID datasheet, TLV7211AID pinout, TLV7211AID application, or TLV7211AID equivalent, key selection criteria include input offset voltage stability over temperature, rail-to-rail common-mode range extending beyond VCC±, push-pull drive capability eliminating external pull-up resistors, and Power-on Reset (POR) behavior ensuring known output state during power transitions.
Technical Context
The TLV7211AID operates from 2.7 V to 15 V single-supply or dual-supply configurations, with rail-to-rail input common-mode voltage range (e.g., –0.3 V to VCC+ + 0.3 V) and internal Power-on Reset holding output low for ~200 µs during VCC ramp-up past 1.7 V. Its push-pull CMOS output drives capacitive loads directly without external components.
It features ultra-low input bias current (0.04 pA typ), high common-mode rejection (75 dB min at 2.7 V), and stable 100 dB voltage gain across operating conditions - enabling precision threshold detection in high-impedance sensor circuits such as optical or magnetic transducers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 15 V - supports wide-input battery and industrial supply rails without external regulation. |
| Input Offset Voltage (max) | 5 mV at 25°C - enables accurate threshold detection in low-voltage analog sensing applications. |
| Supply Current (typ) | 7 μA at 5 V - extends battery life in always-on monitoring circuits like security alarms or wearables. |
| Propagation Delay (tPLH) | 420 ns at 5 V, 100 mV overdrive - ensures fast response for real-time event detection in mobile communications. |
| Input Common-Mode Range | Extends 0.3 V beyond VCC– and VCC+ - allows direct interfacing with sensors operating outside supply rails. |
| Output Type | Push-pull CMOS - eliminates need for external pull-up resistor, reducing BOM count and board space. |
| Power-On Reset | Holds OUT low for ~200 µs after VCC crosses 1.7 V - prevents spurious logic transitions during power sequencing. |
Pinout & Package
TLV7211AID uses the SOIC-8 (D package) with 1.75 mm max height, 3.91 mm × 4.90 mm body, and standard JEDEC MS-012 footprint. Pin 1 is located in quadrant Q1 per tape-and-reel orientation.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | IN– | Inverting input terminal - accepts differential signals up to rail-to-rail common-mode range. |
| 2 | IN+ | Non-inverting input terminal - used for reference or sensor signal connection in comparator configurations. |
| 3 | OUT | CMOS push-pull output - sinks or sources up to 30 mA, compatible with TTL/CMOS logic inputs. |
| 4 | VCC– | Negative supply or ground reference - must be connected; not NC. |
| 5 | NC | No internal connection - left unconnected per TI datasheet. |
| 6 | NC | No internal connection - left unconnected per TI datasheet. |
| 7 | VCC+ | Positive supply input - supports 2.7 V to 15 V operation; decoupling capacitor recommended. |
| 8 | NC | No internal connection - left unconnected per TI datasheet. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input | Common-mode range extends 0.3 V beyond VCC– and VCC+, enabling direct interface with unbuffered sensors. |
| Push-pull output | Drives capacitive loads directly without pull-up resistor - reduces component count and improves rise/fall time. |
| Power-on Reset (POR) | Guarantees known low output state for ~200 µs during power-up, preventing undefined logic states in control systems. |
| Ultra-low input bias current | 0.04 pA typical - preserves signal integrity in high-impedance photodiode or piezoelectric sensor front-ends. |
| Low quiescent current | 7 μA typical at 5 V - supports multi-year battery life in always-on IoT endpoint devices. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar comparator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV7211ID | 15 mV max input offset voltage vs. 5 mV for TLV7211AID - higher threshold uncertainty in precision sensing. | Suitable for cost-sensitive non-critical detection where ±7.5 mV offset tolerance is acceptable. | Select TLV7211ID only when offset drift and accuracy requirements are relaxed; TLV7211AID preferred for sensor front-ends. |
| LMV7211M5X | SC70-5 package (6-pin), 7.5 mV max offset, 1.2 µA supply current - lower power but reduced input voltage range (2.7 V to 5.5 V). | Optimized for ultra-low-power sub-5 V systems; incompatible with 12 V or 15 V supply rails supported by TLV7211AID. | Choose LMV7211M5X only for compact, single-cell battery designs; TLV7211AID remains optimal for wider supply flexibility. |
Compared with TLV7211ID and LMV7211M5X, the TLV7211AID uniquely balances precision (5 mV offset), wide supply range (2.7–15 V), and robust push-pull drive - making it the default choice for industrial and portable systems requiring both accuracy and operational flexibility.

FAQ
What is the maximum supply voltage rating for TLV7211AID?
The absolute maximum supply voltage (VCC+ – VCC–) for TLV7211AID is 16 V, with recommended operating range from 2.7 V to 15 V. Exceeding 16 V risks permanent damage. The device maintains full functionality across this range, including rail-to-rail input operation and stable 7 μA supply current at 5 V - critical for multi-battery or industrial power rail compatibility.
Does TLV7211AID have built-in Power-on Reset (POR) functionality?
Yes, TLV7211AID integrates an internal Power-on Reset circuit that holds the output low for approximately 200 µs after VCC crosses 1.7 V during power-up or power-down. This behavior is confirmed in Section 6.3.2 of the TI datasheet and ensures deterministic startup in microcontroller-based systems - eliminating need for external reset supervision circuits when using TLV7211AID.
Can TLV7211AID replace op-amps used as comparators?
Yes, TLV7211AID is explicitly designed to replace general-purpose op-amps in comparator roles. Its 420 ns propagation delay, push-pull output, and rail-to-rail input deliver superior speed and interface compatibility versus op-amps - while consuming only 7 μA supply current. TI's datasheet confirms this use case in Section 2 Applications, noting TLV7211AID provides "better performance and lower current" than op-amp alternatives.
What is the input offset voltage specification for TLV7211AID over temperature?
TLV7211AID has a maximum input offset voltage of 5 mV at 25°C and 8 mV over the full –40°C to +85°C operating range. Its typical offset temperature drift is 1 μV/°C at 25°C (4 μV/°C at 15 V), ensuring stable threshold accuracy in automotive and industrial environments - a key differentiator from TLV7211ID, which specifies 15 mV max at 25°C.
Is TLV7211AID pin-compatible with other variants in the TLV7211 family?
No - TLV7211AID (SOIC-8) is not pin-compatible with SOT-23-5 (DBV) or SC70-6 (DCK) variants like TLV7211AIDBVR or TLV7211AIDCKR. While functionally identical, package pinouts differ significantly: SOIC-8 has dedicated VCC+, VCC–, IN+, IN–, and OUT pins with four NC terminals, whereas DBV uses a 5-pin linear arrangement. PCB layout must match the specific package variant ordered.
