Texas Instruments TLV27L1ID

Overview

TLV27L1ID from Texas Instruments is a single-channel micropower rail-to-rail output operational amplifier designed for ultra-low-power signal conditioning in industrial-grade systems. It operates from 2.7 V to 16 V, draws only 7 μA per channel, delivers 160 kHz gain-bandwidth, achieves 0.06 V/μs slew rate, and supports −40°C to +125°C operation - ideal for battery-powered power monitoring and portable medical sensors.

For engineers reviewing the TLV27L1ID datasheet, TLV27L1ID pinout, TLV27L1ID application, or TLV27L1ID equivalent, this page provides verified technical context, validated pin functions, real-world use cases in smoke detection and low-power security systems, and two confirmed alternative op-amps with documented functional trade-offs.

Technical Context

The TLV27L1ID uses BiMOS input stage architecture enabling 1 pA typical input bias current and rail-to-rail output swing within 50 mV of each supply rail at ±5 V. Its 160 kHz unity-gain bandwidth and 0.06 V/μs slew rate are optimized for low-frequency precision sensing rather than high-speed signal processing.

It features input common-mode voltage range from −0.2 V to VS−1.2 V, 71 dB minimum CMRR at 25°C, and 74 dB PSRR - making it suitable for single-supply transducer interfaces where headroom and noise rejection are constrained by low-voltage operation.

Key Specifications

FAQ

What is the maximum supply voltage for TLV27L1ID?

The absolute maximum supply voltage for TLV27L1ID is 16.5 V, but the recommended operating range is 2.7 V to 16 V. Exceeding 16 V risks permanent damage. At 16 V, the device maintains rail-to-rail output swing and 7 μA quiescent current - critical for high-voltage industrial sensor interfaces where TLV27L1ID replaces older TLC27L1 variants.

Does TLV27L1ID support rail-to-rail input?

No, TLV27L1ID does not support rail-to-rail input; its input common-mode voltage range is specified from −0.2 V to VS−1.2 V. This means the input cannot go within 1.2 V of the positive rail. However, its rail-to-rail output capability (within 50 mV of both rails at ±5 V) makes TLV27L1ID especially valuable in single-supply configurations where output headroom is critical - such as driving ADC references in portable medical devices.

What is the input bias current of TLV27L1ID at 125°C?

At 125°C, the input bias current of TLV27L1ID is guaranteed ≤1000 pA (1 nA) - a 1000× increase over the 1 pA typical value at 25°C. This temperature-dependent leakage is fully characterized in the datasheet and must be accounted for in high-impedance sensor designs operating at maximum ambient temperature, such as under-hood automotive diagnostics using TLV27L1ID.

Can TLV27L1ID drive capacitive loads?

TLV27L1ID 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., long PCB traces or ADC input capacitance), external isolation resistance (≥100 Ω) is required between TLV27L1ID output and the load to prevent peaking or oscillation - a key layout consideration explicitly called out in the "Circuit Layout Considerations" section of the TLV27L1ID application notes.

Is TLV27L1ID pin-compatible with TLC27L1ID?

Yes, TLV27L1ID is pin-compatible with TLC27L1ID in the SOIC-8 (D) package: both share identical pin 1–8 assignments including NC pins at positions 1, 5, and 8. This allows direct PCB replacement without layout changes. However, TLV27L1ID improves upon TLC27L1ID with 59% lower quiescent current (7 μA vs. 17 μA) and 88% higher bandwidth (160 kHz vs. 85 kHz), making it a true performance upgrade for existing designs still using TLC27L1ID.
