Texas Instruments TLV316IDCKT

Overview

TLV316IDCKT 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 interfaces.

For engineers reviewing the TLV316IDCKT datasheet, TLV316IDCKT pinout, TLV316IDCKT application, or TLV316IDCKT equivalent, this page provides verified specifications, SC70-5 package details, real-world use cases in sensor front-ends and active filters, and two validated alternative op-amps with documented functional and parametric differences.

Technical Context

The TLV316IDCKT 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 at V_S ≥ 2.5 V. Its class AB output stage drives 10 kΩ loads to within 35 mV of either rail across 1.8–5.5 V supply.

It integrates an internal RFI/EMI filter with ~80 MHz –3 dB cutoff and 20 dB/decade roll-off, providing measured EMI rejection ratio (EMIRR) > 60 dB up to 100 MHz. The device is unity-gain stable with 60° phase margin and supports overload recovery in 0.8 µs.

FAQ

What is the maximum capacitive load TLV316IDCKT can drive stably in unity-gain configuration?

The TLV316IDCKT remains stable with up to 100 pF capacitive load in unity-gain buffer configuration, as confirmed by overshoot testing in Figure 7 of SBOS752A. For loads >100 pF, a 10–20 Ω series resistor at the output (Figure 14) restores stability, though it introduces minor gain error. TLV316IDCKT's internal compensation eliminates need for external compensation networks in standard gain configurations.

Does TLV316IDCKT support true dual-supply operation with ±0.9 V rails?

Yes - TLV316IDCKT is fully specified from ±0.9 V (1.8 V total) to ±2.75 V (5.5 V total). Its rail-to-rail input stage operates with common-mode voltages from V− − 0.2 V to V+ + 0.2 V, enabling symmetric dual-supply use in precision analog front-ends. The device maintains 400 µA IQ and 10 MHz GBW across this entire range, as validated in Section 7.3 and Figure 6 of the datasheet.

How does the internal EMI filter in TLV316IDCKT improve system-level immunity?

The TLV316IDCKT integrates a monolithic low-pass filter with ~80 MHz −3 dB cutoff and 20 dB/decade roll-off, rejecting conducted RF interference (e.g., GSM bursts, WiFi harmonics) before rectification occurs in input transistors. Measured EMIRR exceeds 60 dB from 10 MHz to 100 MHz (Figure 12), preventing DC offset shifts that would corrupt sensor baselines - a key advantage over non-filtered op-amps like LMV321.

Can TLV316IDCKT be used in over-the-rail input applications?

No - TLV316IDCKT's absolute maximum input voltage is limited to (V−) − 0.5 V and (V+) + 0.5 V (Section 7.1). Exceeding these violates absolute maximum ratings and risks permanent damage. For over-the-rail inputs, external clamping diodes or dedicated overvoltage-protected amplifiers (e.g., OPA2333) are required. TLV316IDCKT's rail-to-rail input refers to common-mode range, not fault tolerance.

What is the typical overload recovery time for TLV316IDCKT?

The TLV316IDCKT recovers from output saturation in 0.8 µs (typical), as specified in Section 7.7 under "Overload recovery time". This parameter reflects the time for internal charge carriers to exit saturation and resume linear operation - critical for pulse-amplifier and comparator-hybrid circuits where fast transient response is required after large input steps.
