Texas Instruments TLV9001SIDCKR

Overview

TLV9001SIDCKR from Texas Instruments is a single-channel, rail-to-rail input/output operational amplifier optimized for low-power, cost-sensitive systems operating from 1.8 V to 5.5 V supply. It delivers ±0.4 mV input offset voltage, 1 MHz unity-gain bandwidth, 60 µA quiescent current per channel, and 27 nV/√Hz broadband noise-enabling precision signal conditioning in wearable devices and smoke detectors.

For engineers reviewing the TLV9001SIDCKR datasheet, TLV9001SIDCKR pinout, TLV9001SIDCKR application, or TLV9001SIDCKR equivalent, key selection criteria include its SC70-6 (DCK) package footprint, integrated RFI/EMI filter, resistive open-loop output impedance for high capacitive-load stability (up to 500 pF), shutdown capability (<1 µA standby), and operation across –40°C to +125°C.

Technical Context

The TLV9001SIDCKR implements a scalable CMOS architecture with unity-gain stability and no phase reversal under overdrive. Its resistive open-loop output impedance simplifies compensation with capacitive loads up to 500 pF-critical for sensor front-ends driving long traces or ADC input filters.

It integrates an internal RFI/EMI rejection filter and supports shutdown mode via dedicated SHDN pin, reducing total supply current to <1 µA. The device operates down to 1.8 V, enabling direct interface with Li-ion battery–powered microcontrollers and low-voltage analog sensors.

FAQ

What is the maximum capacitive load the TLV9001SIDCKR can drive while maintaining stability?

The TLV9001SIDCKR is characterized to drive up to 500 pF capacitive load while remaining unity-gain stable, thanks to its resistive open-loop output impedance. This eliminates the need for external isolation resistors in ADC driver or filter applications. For loads exceeding 500 pF, stability must be verified per layout and feedback network; the TLV9001SIDCKR datasheet provides recommended compensation guidelines in Section 9.2.

Does the TLV9001SIDCKR support single-supply operation?

Yes, the TLV9001SIDCKR fully supports single-supply operation from 1.8 V to 5.5 V, with rail-to-rail input and output swing. Its input common-mode range extends 0.1 V beyond both rails, and output swings within 5 mV of each rail under light load-making it ideal for interfacing with 3.3 V or 1.8 V microcontrollers and ADCs without level-shifting circuitry.

How does the shutdown feature of the TLV9001SIDCKR function?

The TLV9001SIDCKR's SHDN pin is active-high: applying logic high (≥0.7 × V+) enables normal operation, while logic low (≤0.3 × V+) places the amplifier in shutdown mode with typical supply current <1 µA. Internal pull-up ensures defined state on power-up; no external pull-up resistor is required. Shutdown recovery time is <15 µs, enabling rapid wake-up in event-driven sensing systems.

Is the TLV9001SIDCKR compatible with lead-free reflow profiles?

Yes, the TLV9001SIDCKR in SC70 (DCK) package is rated for standard lead-free reflow per JEDEC J-STD-020, with peak reflow temperature up to 260°C. Its moisture sensitivity level (MSL) is 1, meaning unlimited floor life at ≤30°C/85% RH-eliminating bake requirements before assembly. Thermal characteristics are validated per the datasheet's Table 7.5 (Thermal Information: TLV9001S).

What is the input voltage noise density of the TLV9001SIDCKR, and how does it impact sensor signal integrity?

The TLV9001SIDCKR has a broadband input voltage noise density of 27 nV/√Hz at 1 kHz. In a 10 kHz bandwidth, this translates to ~0.85 µV_RMS integrated noise-sufficient for preserving signal integrity in millivolt-level sensor outputs such as thermopiles or strain gauges. Combined with 5 pA input bias current and ±0.4 mV offset, it maintains <0.1% total error in precision current-sense and bridge-amplifier applications.
