Texas Instruments TLV9061IDCKR

Overview

TLV9061IDCKR from Texas Instruments is a single-channel, rail-to-rail input/output CMOS operational amplifier optimized for cost-sensitive, low-voltage systems. It delivers 10MHz unity-gain bandwidth, ±0.3mV typical input offset voltage, 10nV/√Hz input voltage noise, 538µA quiescent current, and operates from 1.8V to 5.5V supply. It is used in low-side current sensing and wearable device signal conditioning where precision, low power, and small size are critical.

For engineers reviewing the TLV9061IDCKR datasheet, TLV9061IDCKR pinout, TLV9061IDCKR application, or TLV9061IDCKR equivalent, this page provides verified electrical specifications, SC70-5 package details, real-world use cases in HVAC and e-bikes, and validated alternative op-amps with documented functional trade-offs.

Technical Context

The TLV9061IDCKR employs a CMOS input stage enabling ultra-low input bias current (0.5pA) and rail-to-rail common-mode input range extending 0.1V beyond both supply rails. Its resistive open-loop output impedance simplifies stability with capacitive loads up to 100pF without external compensation.

It features internal RFI/EMI filtering and no phase reversal under overdrive - critical for sensor front-ends in noisy industrial environments. The device is unity-gain stable and specified across –40°C to +125°C, supporting automotive cabin modules and motor control feedback loops.

FAQ

What is the maximum capacitive load the TLV9061IDCKR can drive without external compensation?

The TLV9061IDCKR is characterized for stable operation with up to 100pF capacitive load due to its resistive open-loop output impedance. Its design eliminates the need for series isolation resistors typically required by conventional op-amps, simplifying layout in ADC driver and filter applications. This capability is confirmed in the datasheet's Figure 6-23 (Small-Signal Overshoot vs Load Capacitance) and Section 7.3.

Does the TLV9061IDCKR support single-supply operation down to 1.8V?

Yes, the TLV9061IDCKR is fully specified for single-supply operation from 1.8V to 5.5V. Its rail-to-rail input stage accepts common-mode voltages from (V–) – 0.1V to (V+) + 0.1V, and its output swings within 20mV of both rails at 5.5V/10kΩ - enabling full utilization of low-voltage ADC reference ranges. This is validated in Section 6.3 (Recommended Operating Conditions) and Table 6-10.

What is the shutdown current consumption of the TLV9061IDCKR?

The TLV9061IDCKR does not include a shutdown pin; only the TLV9061S variants (e.g., TLV9061SIDCKR) feature shutdown functionality. For TLV9061IDCKR, quiescent current remains at 538µA (typ) across the full 1.8V–5.5V supply range and –40°C to +125°C temperature range, as specified in Table 6-10 (Electrical Characteristics).

How does the internal RFI/EMI filter in the TLV9061IDCKR improve system robustness?

The internal RFI/EMI filter in the TLV9061IDCKR attenuates high-frequency interference (e.g., GSM bursts, switch-mode power supply noise) before it reaches the input stage, reducing susceptibility without requiring external RC networks. This is especially valuable in automotive and industrial settings where conducted emissions can corrupt sensor signals - a feature explicitly called out in the "Features" section and Section 7.3 of the datasheet.

Is the TLV9061IDCKR pin-compatible with other SC70-5 op-amps like the OPA316IDBVR?

Yes, TLV9061IDCKR and OPA316IDBVR share identical SC70-5 (DCK) packaging and pinout: Pin 1 = IN+, Pin 2 = V–, Pin 3 = IN–, Pin 4 = OUT, Pin 5 = V+. This allows direct physical replacement in existing layouts, though functional validation is required due to differences in offset voltage, noise, and EMI filtering - as detailed in the Equivalent & Alternatives section.
