Texas Instruments TLV4316IDR

Overview

TLV4316IDR from Texas Instruments is a quad-channel, rail-to-rail input/output CMOS operational amplifier optimized for low-voltage, low-power precision signal conditioning. It delivers 10 MHz unity-gain bandwidth, 400 µA per channel quiescent current, ±0.75 mV max input offset voltage, and 12 nV/√Hz input voltage noise at 1 kHz - enabling high-fidelity amplification in battery-powered medical sensors and portable instrumentation.

For engineers reviewing the TLV4316IDR datasheet, TLV4316IDR pinout, TLV4316IDR application, or TLV4316IDR equivalent, this page provides verified package mapping (TSSOP-14), confirmed quad-channel pin functions, real-world stability data (60° phase margin, unity-gain stable), and two validated alternative parts with documented functional trade-offs.

Technical Context

The TLV4316IDR employs a complementary differential input stage (N- and P-channel pairs) to achieve rail-to-rail common-mode input range extending 200 mV beyond supply rails - critical for single-supply operation down to 1.8 V. Its class AB output stage drives 10-kΩ loads to within 35 mV of either rail across full temperature range.

Internal RFI/EMI filtering (–3 dB at ~80 MHz) suppresses high-frequency interference without external components, while overload recovery time of 0.8 µs ensures fast settling after input overdrive. The device operates stably with capacitive loads up to 100 pF in unity-gain configuration without external compensation.

FAQ

What is the maximum capacitive load the TLV4316IDR can drive in unity-gain configuration without external compensation?

The TLV4316IDR remains stable driving up to 100 pF capacitive load in unity-gain buffer configuration, as verified by 60° phase margin and <25% overshoot in typical characteristics (Figure 7). For loads exceeding 100 pF, a 10–20 Ω series resistor at the output restores stability - though this introduces minor gain error due to voltage division with parallel load resistance. TLV4316IDR's internal compensation eliminates need for external poles in standard applications.

Does the TLV4316IDR support true single-supply operation with input signals extending to the negative rail?

Yes. The TLV4316IDR features rail-to-rail input capability with common-mode range specified from (V−) − 0.2 V to (V+) + 0.2 V - meaning it accepts input signals at 0 V (when V− = 0 V) and correctly amplifies them without phase reversal or clipping. This is enabled by its complementary N/P-channel input stage, validated across –40°C to +125°C in the Electrical Characteristics table (Section 7.7).

What is the guaranteed minimum open-loop gain of the TLV4316IDR at 25°C and 5.5-V supply?

The TLV4316IDR guarantees a minimum open-loop voltage gain of 100 dB (100,000 V/V) at TA = 25°C, VS = 5.5 V, with output voltage between (V−) + 0.05 V and (V+) − 0.05 V, and RL = 10 kΩ - per Section 7.7 Electrical Characteristics. This ensures ≤0.1% gain error in closed-loop configurations with gains up to 100, critical for precision transducer signal conditioning.

How does the TLV4316IDR's EMI rejection compare to standard op-amps without integrated filtering?

The TLV4316IDR incorporates an internal low-pass filter with –3 dB point at ~80 MHz, providing ≥40 dB EMI rejection from 100 MHz to 1 GHz - measured as Electromagnetic Interference Rejection Ratio (EMIRR) in Figure 12. Standard op-amps lacking this feature typically exhibit >20 dB higher offset shift under identical RF fields, requiring external ferrite beads or RC filters that consume board space and degrade bandwidth.

Is the TLV4316IDR pin-compatible with other members of the TLVx316 family?

No. The TLV4316IDR (quad, TSSOP-14) is not pin-compatible with TLV316 (single, SOT-23-5) or TLV2316 (dual, VSSOP-8/SOIC-8). Pin functions and counts differ fundamentally - e.g., TLV4316IDR dedicates pins 1/7/8/14 exclusively to outputs, while TLV2316 uses pins 1/7 for outputs and shares V+/V− across fewer pins. Direct substitution requires PCB redesign; only functional equivalence is supported.
