Product details
Overview
TLV27L1IDR from Texas Instruments is a single-channel micropower rail-to-rail output operational amplifier designed for ultra-low-power sensing and signal conditioning in battery-operated systems. It delivers 160 kHz gain-bandwidth, 0.1 V/μs slew rate, 7 μA supply current per channel, 89 nV/√Hz input voltage noise, and operates from 2.7 V to 16 V across −40°C to 125°C - enabling use in portable medical monitors and industrial smoke detectors.
For engineers reviewing the TLV27L1IDR datasheet, TLV27L1IDR pinout, TLV27L1IDR application, or TLV27L1IDR equivalent, key selection criteria include its BiMOS rail-to-rail output architecture, 1 pA input bias current, industrial temperature rating, SOIC-8 packaging, and compatibility with single-supply sensor front-ends requiring low quiescent power and wide supply range.
Technical Context
The TLV27L1IDR employs a BiMOS input stage enabling 1 pA typical input bias current and rail-to-rail output swing within 50 mV of each rail at ±5 V supply. Its 160 kHz unity-gain bandwidth is achieved with only 7 μA quiescent current, making it suitable for DC-coupled precision amplification where power budget constraints preclude higher-speed op-amps.
It features a CMRR of 71 dB (min) and PSRR of 74 dB (min) over the full industrial temperature range, with input offset voltage specified at 5 mV (max) and drift of 1.1 μV/°C - supporting stable operation in unregulated or thermally varying environments without external trimming.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 16 V - supports single-cell LiFePO₄ (2.8–3.6 V), dual alkaline (2.4–3.2 V), or ±8 V split supplies. |
| Quiescent Current | 7 μA per channel - enables >1-year battery life in 10-μA average-power smoke detector signal chains. |
| Gain Bandwidth Product | 160 kHz - sufficient for anti-aliasing filtering and DC-coupled sensor amplification up to ~100 kHz. |
| Input Bias Current | 1 pA (typ) - minimizes voltage error in high-impedance pH or photodiode transimpedance circuits. |
| Input Voltage Noise | 89 nV/√Hz at 1 kHz - suitable for low-frequency biomedical signal conditioning without dominant noise contribution. |
| Rail-to-Rail Output | Swings within 50 mV of rails at ±5 V - maximizes dynamic range in 3.3 V or 5 V ADC interfaces. |
| Operating Temperature | −40°C to 125°C - qualified for under-hood automotive or industrial process monitoring applications. |
Pinout & Package
TLV27L1IDR is housed in an 8-pin SOIC (D package) with standard op-amp pinout and no internal connections on pins 1, 5, and 8. The package measures 4.9 mm × 3.9 mm × 1.75 mm and is RoHS-compliant with NiPdAu lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | No connect | Unused pin; must be left floating or tied to GND for mechanical stability - no electrical function. |
| 2 | Inverting input (IN−) | Differential input node; high-impedance BiMOS input with 1 pA bias current enables precision feedback networks. |
| 3 | Non-inverting input (IN+) | Reference input node; common-mode range extends to −0.2 V below GND and up to VS−1.2 V. |
| 4 | Ground (GND) | Power return reference; requires low-inductance connection to ground plane to maintain PSRR and stability. |
| 5 | No connect | Unused pin; electrically isolated - no internal bond wire or circuit connection. |
| 6 | Output (OUT) | Rail-to-rail output capable of sourcing/sinking ≥400 μA while maintaining linearity near supply rails. |
| 7 | Positive supply (VDD) | Single or positive rail input; accepts 2.7–16 V; decoupling with 0.1 μF ceramic capacitor required within 0.1 inch. |
| 8 | No connect | Unused pin; no internal connection - not intended for power, ground, or control functions. |
Key Features
| Feature | Design Value |
|---|---|
| BiMOS rail-to-rail output | Delivers full output swing (within 50 mV of rails) without sacrificing speed or quiescent current - critical for maximizing ADC resolution in low-voltage systems. |
| 1 pA input bias current | Enables accurate amplification of signals from high-impedance sources (e.g., electrochemical sensors) without significant input loading error. |
| 160 kHz bandwidth at 7 μA | Provides usable AC response for slow-varying industrial signals while consuming less than 17 μW at 2.7 V - ideal for always-on monitoring nodes. |
| −40°C to 125°C operation | Guarantees parametric performance across extended industrial temperature range - eliminates need for derating or thermal compensation in harsh environments. |
| SOIC-8 tape-and-reel packaging | Standard 2500-unit reel format (12.4 mm tape width, Q1 pin-1 quadrant) supports automated SMT assembly without custom handling. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLC27L1IDR | Higher 17 μA quiescent current, narrower 85 kHz GBW, no rail-to-rail output (swing limited to VS−1.5 V). | Not suitable for 3.3 V ADC interfacing or ultra-low-power designs requiring >5-year battery life. | Select TLV27L1IDR when rail-to-rail output, lower IQ, or wider bandwidth is required; TLC27L1IDR may be used only if legacy PCB layout mandates pin compatibility. |
| OPA349AIDBVR | Lower 2 μA IQ and 1.8 V min supply, but only 70 kHz GBW and 300 nV/√Hz input noise - optimized for sub-1 V systems. | Better for 1.8 V microcontroller domains; unsuitable for 5 V or 12 V industrial signal chains due to voltage limits. | Choose OPA349AIDBVR for <2 V supply applications; TLV27L1IDR remains preferred for 2.7–16 V operation with balanced noise/bandwidth/power. |
Compared with TLC27L1IDR and OPA349AIDBVR, TLV27L1IDR uniquely balances 160 kHz bandwidth, rail-to-rail output, 7 μA IQ, and −40°C to 125°C operation - making it the optimal choice for industrial and portable systems requiring wide supply range and precision at micropower levels.

FAQ
What is the maximum supply voltage for TLV27L1IDR?
The absolute maximum supply voltage for TLV27L1IDR is 16.5 V, with recommended operation up to 16 V. Exceeding this risks permanent damage. The device supports dual-supply operation down to ±1.35 V and single-supply operation from 2.7 V to 16 V - making TLV27L1IDR compatible with both low-voltage portable systems and higher-voltage industrial rails.
Does TLV27L1IDR support rail-to-rail input?
No, TLV27L1IDR does not support rail-to-rail input. Its input common-mode voltage range is specified from −0.2 V to VS−1.2 V. While the output swings rail-to-rail (within 50 mV of each rail), the inputs require at least 1.2 V headroom below the positive rail. This limitation must be considered when designing non-inverting amplifiers or level-shifting circuits using TLV27L1IDR.
What is the input offset voltage specification for TLV27L1IDR?
The input offset voltage for TLV27L1IDR is guaranteed to be ≤5 mV over the full −40°C to 125°C temperature range, with a typical value of 0.5 mV at 25°C. Its offset voltage drift is 1.1 μV/°C, ensuring minimal drift-induced error in precision DC amplification stages - a key parameter distinguishing TLV27L1IDR from older TLC27Lx variants.
Can TLV27L1IDR drive capacitive loads directly?
TLV27L1IDR can drive up to 50 pF load capacitance while maintaining ≥62° phase margin, as verified in Figure 16 of the datasheet. For larger capacitive loads (e.g., ADC input filters), a series isolation resistor (≥100 Ω) is recommended between TLV27L1IDR output and the capacitor to preserve stability. Uncompensated direct driving of >100 pF loads may cause ringing or oscillation.
Is TLV27L1IDR pin-compatible with other SOIC-8 op-amps?
TLV27L1IDR uses standard SOIC-8 pinout (IN−, IN+, GND, OUT, NC, VDD, NC, NC) and is pin-compatible with industry-standard single op-amps like LM358 and TLC27L1 in the D package. However, functional compatibility requires verification of supply range, output swing, and quiescent current - TLV27L1IDR's rail-to-rail output and 7 μA IQ differ significantly from LM358 (1.2 mA IQ) and TLC27L1 (17 μA IQ).
