Texas Instruments TLV316IDCKR

Overview

TLV316IDCKR 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 TLV316IDCKR datasheet, TLV316IDCKR pinout, TLV316IDCKR application, or TLV316IDCKR equivalent, key selection considerations include its 1.8 V to 5.5 V supply range, ±10 pA input bias current for high-impedance sensor interfacing, rail-to-rail output swing within 35 mV of rails (RL = 10 kΩ), and integrated RFI/EMI filter with ~80 MHz cutoff.

Technical Context

The TLV316IDCKR employs a complementary input stage (N- and P-channel differential pairs) enabling rail-to-rail common-mode input range extending 200 mV beyond both supply rails at VS > 2.5 V. Its class AB output stage supports full rail-to-rail swing into 10-kΩ loads while maintaining stability with capacitive loads up to 100 pF in unity-gain configuration.

It features an internal single-pole low-pass EMI filter (–3 dB at ~80 MHz) providing common-mode and differential-mode rejection, and exhibits no phase reversal under overdrive. Overload recovery time is 0.8 µs, and open-loop gain exceeds 100 dB across its operating temperature range.

Key Specifications

Pinout & Package

TLV316IDCKR is housed in a 5-pin SC70 package (1.25 mm × 2.00 mm body size), optimized for space-constrained portable designs. Thermal resistance R_θJA is 263.3°C/W, requiring minimal PCB copper area for thermal management in ambient temperatures up to +125°C.

FAQ

What is the maximum capacitive load the TLV316IDCKR can drive stably in unity-gain configuration?

The TLV316IDCKR is specified for stable operation with up to 100 pF capacitive load in unity-gain buffer configuration. For larger loads, a series output resistor (10–20 Ω) is recommended to maintain ≥40° phase margin and prevent overshoot. This behavior is validated in Figure 7 of the SBOS752A datasheet, which shows small-signal overshoot vs. capacitive load for TLV316IDCKR.

Does the TLV316IDCKR support true single-supply operation down to 1.8 V?

Yes, TLV316IDCKR is fully specified and tested from 1.8 V to 5.5 V supply voltage. Its rail-to-rail input extends 200 mV beyond both rails (V− − 0.2 V to V+ + 0.2 V), and output swings to within 35 mV of either rail with 10-kΩ load - enabling direct interface with 1.8-V ADCs and microcontrollers without level-shifting circuitry.

How does the internal EMI filter in TLV316IDCKR improve system-level robustness?

The TLV316IDCKR integrates a single-pole low-pass filter with ~80 MHz –3 dB point on both inputs, rejecting conducted RF interference from cellular, Wi-Fi, and Bluetooth bands. Measured EMIRR exceeds 60 dB at 900 MHz, preventing rectified offsets that cause baseline drift in sensitive analog front-ends - eliminating need for external ferrite beads or RC filters in compact layouts.

What is the typical input offset voltage drift over temperature for TLV316IDCKR?

The TLV316IDCKR exhibits ±2 µV/°C typical input offset voltage drift across –40°C to +125°C, as specified in Section 7.7 of SBOS752A. This low drift, combined with ±0.75 mV max initial offset at 25°C, reduces calibration frequency in precision measurement systems operating across wide ambient conditions.

Is TLV316IDCKR pin-compatible with other members of the TLVx316 family?

No - TLV316IDCKR (single, SC70-5) is not pin-compatible with TLV2316 (dual, 8-pin) or TLV4316 (quad, 14-pin). However, its SC70-5 pinout matches TLV316 variants in same package (e.g., TLV316IDBVR in SOT-23-5 uses identical pin numbering but different footprint). Always verify mechanical dimensions and thermal pad presence before substitution.
