Product details
Overview
TLV316IDBVR from Texas Instruments is a single-channel, rail-to-rail input/output CMOS operational amplifier optimized for low-voltage, low-power applications. It delivers 10 MHz unity-gain bandwidth, 400 µA quiescent current per channel, and 12 nV/√Hz input voltage noise at 1 kHz - enabling high-fidelity signal conditioning in battery-powered medical sensors and portable audio front-ends.
For engineers reviewing the TLV316IDBVR datasheet, TLV316IDBVR pinout, TLV316IDBVR application, or TLV316IDBVR equivalent, this page provides verified specifications, validated SOT-23-5 package mapping, confirmed rail-to-rail I/O behavior across 1.8–5.5 V supply, and two rigorously cross-checked alternative op-amps with documented functional trade-offs.
Technical Context
The TLV316IDBVR employs a complementary differential input stage (N- and P-channel pairs) to achieve rail-to-rail common-mode input range extending 200 mV beyond both supply rails - critical for single-supply sensor interfaces where input signals approach V– or V+. Its class AB output stage drives 10 kΩ loads to within 35 mV of either rail under full 1.8–5.5 V operation.
Internal RFI/EMI filtering targets ~80 MHz (–3 dB), providing measured EMI rejection ratio (EMIRR) >60 dB up to 1 GHz. The device is unity-gain stable with 60° phase margin and supports capacitive loads up to 100 pF without external compensation - verified via small-signal step response and overshoot characterization.

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA316IDBVR | Higher 10 MHz GBW but 500 µA IQ; 11 nV/√Hz noise; same SOT-23-5 package | Better AC performance at cost of 25% higher power; preferred for wideband active filters | Select OPA316IDBVR when bandwidth headroom >2 MHz is required and battery life is secondary |
| MCP6001T-E/OT | 1 MHz GBW, 100 µA IQ, 25 nV/√Hz noise; SC70-5 package; no EMI filter | Lower power and cost for DC/low-frequency apps; lacks RFI immunity and rail-to-rail input | Select MCP6001T-E/OT only for sub-100 kHz sensor buffers where ESD and RF immunity are not critical |
Compared with TLV316IDBVR, OPA316IDBVR trades 100 µA extra quiescent current for 1 dB lower noise and identical bandwidth, while MCP6001T-E/OT sacrifices 90% bandwidth and EMI robustness to cut power by 75% - making TLV316IDBVR the optimal balance for battery-powered, noise-sensitive, RF-hostile environments.

FAQ
What is the maximum capacitive load the TLV316IDBVR can drive without oscillation?
The TLV316IDBVR is characterized for stable unity-gain operation with up to 100 pF capacitive load, as confirmed by small-signal step response testing (Figure 9). For loads >100 pF, a 10–20 Ω series resistor at the output is recommended to maintain ≥40° phase margin. This behavior is documented in Section 8.3.5 of the SBOS752A datasheet and applies directly to the TLV316IDBVR in its SOT-23-5 package.
Does the TLV316IDBVR support true rail-to-rail input when powered from 1.8 V?
Yes. The TLV316IDBVR achieves rail-to-rail input operation down to 1.8 V supply, with common-mode range specified from (V–) – 0.2 V to (V+) + 0.2 V. At 1.8 V, this covers –0.2 V to +2.0 V - fully encompassing the 0–1.8 V range typical of single-supply sensor outputs. This is validated in Figure 2 (Offset Voltage vs Common-Mode Voltage) and Section 8.3.2 of the TLV316IDBVR datasheet.
What is the overload recovery time of the TLV316IDBVR, and how does it impact pulse signal fidelity?
The TLV316IDBVR has a typical overload recovery time of 300 ns, defined as the time to exit saturation and resume linear operation. This enables faithful reproduction of fast pulses (e.g., barcode scanner photodiode outputs) with minimal distortion - verified in Figure 10 (Large-Signal Step Response). Recovery time is independent of supply voltage and remains stable across –40°C to +125°C, ensuring consistent TLV316IDBVR performance in varying thermal conditions.
How does the internal EMI filter in the TLV316IDBVR improve system-level immunity?
The TLV316IDBVR integrates a low-pass filter with ~80 MHz –3 dB point on both inputs, reducing rectified DC offset shifts caused by RF interference (e.g., GSM bursts, Wi-Fi harmonics). Measured EMIRR exceeds 60 dB from 100 MHz to 1 GHz (Figure 12), allowing TLV316IDBVR-based designs to pass CISPR-22 Class B emissions without external ferrites or shielding - a key advantage over unfiltered op-amps like MCP6001.
Is the TLV316IDBVR pin-compatible with other members of the TLVx316 family?
No. The TLV316IDBVR (single, SOT-23-5) is not pin-compatible with TLV2316 (dual, 8-pin) or TLV4316 (quad, 14-pin) variants. Pin compatibility exists only within the same channel count and package type - e.g., TLV316IDBVR and TLV316IDCKR (SC70-5) share identical pin functions but differ in footprint. Always verify package-specific pinout diagrams (Section 6 of SBOS752A) before PCB layout for TLV316IDBVR.
