Product details
Overview
TLV9001QDBVRQ1 from Texas Instruments is an AEC-Q100 Grade 1 qualified automotive operational amplifier with rail-to-rail input/output, 1 MHz unity-gain bandwidth, ±0.4 mV input offset voltage, and 60 µA per-channel quiescent current. It operates from 1.8 V to 5.5 V and delivers robust performance in low-side current sensing, infotainment signal conditioning, and ADAS sensor front-ends.
For engineers reviewing the TLV9001QDBVRQ1 datasheet, TLV9001QDBVRQ1 pinout, TLV9001QDBVRQ1 application, or TLV9001QDBVRQ1 equivalent, this page provides verified functional context, validated pin-level design meaning, confirmed automotive-grade thermal and ESD specs, and real-world application constraints for single-supply precision amplification in safety-critical vehicle systems.
Technical Context
The TLV9001QDBVRQ1 implements a complementary-input CMOS architecture enabling true rail-to-rail input operation - extending 100 mV beyond both supply rails across 1.8 V–5.5 V - and a class-AB output stage delivering 20 mV rail-to-rail swing into 10 kΩ. Its resistive open-loop output impedance (1.2 kΩ at 1 MHz) simplifies stability with capacitive loads up to 500 pF.
It features integrated RFI/EMI filtering (EMIRR+ > 100 dB at 100 MHz), no phase reversal under overdrive, and functional safety capability documentation per ISO 26262. All electrical characteristics are specified over –40°C to +125°C ambient temperature with AEC-Q100 HBM ±2 kV and CDM ±1 kV ESD ratings.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 1.8 V to 5.5 V - enables direct interface with 2.5 V, 3.3 V, and 5 V automotive microcontrollers and ADCs without level-shifting. |
| Unity-Gain Bandwidth | 1 MHz - supports stable closed-loop gain ≥1 configurations for DC-coupled sensor amplification and anti-aliasing filtering. |
| Input Offset Voltage | ±0.4 mV (typ) - ensures ≤0.2% error in 200 mV full-scale current-sense applications without trimming. |
| Quiescent Current | 60 µA per channel - allows battery-backed always-on monitoring circuits in body control modules with <1 µA total system standby impact. |
| Input Bias Current | ±5 pA - minimizes voltage error across high-impedance source networks (e.g., thermistor bridges, piezoelectric sensors). |
| Output Swing | Within 20 mV of rails (RL = 10 kΩ) - maximizes dynamic range for 12-bit+ ADCs operating on single 3.3 V or 5 V supplies. |
| Open-Loop Output Impedance | 1.2 kΩ (at 1 MHz) - enables stable operation with ≥500 pF capacitive loads without external isolation resistors. |
Pinout & Package
TLV9001QDBVRQ1 is packaged in a 5-pin SOT-23 (DBV) with 1.60 mm × 2.90 mm body size, optimized for space-constrained automotive PCBs and reflow-compatible assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1: OUT | Amplifier output | Class-AB buffered node capable of sourcing/sinking ±40 mA; rail-to-rail swing into 10 kΩ; resistive ZO enables direct drive of 500 pF loads. |
| 2: V− | Negative supply / ground reference | Accepts 0 V (single-supply) or negative rail; internal ESD diodes clamp ±0.5 V beyond rails; must be decoupled within 2 mm of pin. |
| 3: IN+ | Noninverting input | High-impedance CMOS node (5 pA bias); common-mode range extends (V−) −0.1 V to (V+) +0.1 V; complementary input pair eliminates phase reversal. |
| 4: IN− | Inverting input | Matches IN+ in voltage range and bias current; used for precision differential gain configurations and active filters requiring matched input impedances. |
| 5: V+ | Positive supply | Accepts 1.8 V–5.5 V; PSRR > 80 dB (DC) ensures immunity to power rail noise in noisy automotive environments. |

FAQ
What is the maximum capacitive load the TLV9001QDBVRQ1 can drive while maintaining stability?
The TLV9001QDBVRQ1 is characterized to remain stable with up to 500 pF capacitive load in unity-gain configuration due to its resistive open-loop output impedance. This eliminates the need for external series resistors in typical ADC driver or cable-drive applications. Measured phase margin stays above 60° up to 500 pF, and small-signal overshoot remains below 15% - verified per Figure 6-24 and 6-26 of the SBOS980G datasheet. TLV9001QDBVRQ1 maintains this behavior across –40°C to +125°C.
Does TLV9001QDBVRQ1 support true rail-to-rail input common-mode voltage range?
Yes, TLV9001QDBVRQ1 supports rail-to-rail input with common-mode voltage range from (V−) −0.1 V to (V+) +0.1 V across its full 1.8 V–5.5 V supply range. This is achieved via a complementary N/P-channel input stage that transitions seamlessly - no phase reversal occurs even when inputs exceed rails by 100 mV. Performance parameters (PSRR, CMRR, offset) are guaranteed across this full range except in a narrow transition region near (V+) −1.2 V to (V+) −1.0 V, where minor degradation may occur.
What is the overload recovery time specification for TLV9001QDBVRQ1?
The overload recovery time for TLV9001QDBVRQ1 is 850 ns (typical), measured from output saturation to linear operation under G = −10, 600 mVpp input step (Figure 6-28). This fast recovery prevents signal distortion in pulse-width modulated systems and ensures accurate capture of transient events in current-sense or sensor-monitoring applications. Recovery time remains consistent across –40°C to +125°C and all valid supply voltages.
Is TLV9001QDBVRQ1 compatible with 1.8 V logic and mixed-voltage systems?
Yes, TLV9001QDBVRQ1 is fully specified down to 1.8 V supply (±0.9 V), with guaranteed operation of all key parameters - including 1 MHz GBW, ±0.4 mV offset, and rail-to-rail I/O - at this minimum voltage. Its input common-mode range extends to (V−) −0.1 V, allowing direct interface with 1.8 V microcontroller GPIOs and ADC references. The device draws only 60 µA at 1.8 V, making it ideal for battery-powered automotive subsystems.
How does the integrated RFI/EMI filter in TLV9001QDBVRQ1 improve system-level EMC performance?
The integrated RFI/EMI filter in TLV9001QDBVRQ1 provides >100 dB rejection at 100 MHz (Figure 6-35), directly suppressing cellular, Bluetooth, and keyless entry interference before it corrupts analog signals. Unlike external RC filters, this on-die solution preserves DC accuracy, phase response, and bandwidth - critical for real-time ADAS and infotainment functions. TLV9001QDBVRQ1's EMIRR+ performance eliminates need for board-level shielding or ferrite beads in most automotive signal chains.
