Texas Instruments TLV9152IDGKR

Overview

TLV9152IDGKR from Texas Instruments is a dual-channel, rail-to-rail input/output operational amplifier optimized for precision industrial signal conditioning. It delivers ±125 µV offset voltage, 4.5-MHz gain-bandwidth product, 20 V/µs slew rate, and operates from 2.7 V to 16 V supply. It is used in high-side current sensing and factory automation analog front-ends where low noise (10.5 nV/√Hz) and robust EMI rejection are critical.

For engineers reviewing the TLV9152IDGKR datasheet, TLV9152IDGKR pinout, TLV9152IDGKR application, or TLV9152IDGKR equivalent, this page provides verified specifications, dual-channel pin mapping for VSSOP-8, real-world use cases in test equipment and current sensing, and two validated alternative op amps with documented functional trade-offs.

Technical Context

The TLV9152IDGKR implements a precision bipolar-input architecture with differential and common-mode input voltage range extending to both supply rails. Its internal design integrates EMI/RFI filtering on input pins and supports shutdown control per channel in variants - though the DGKR package lacks shutdown functionality.

It achieves 120 dB common-mode rejection and ±0.3 µV/°C offset drift across –40°C to 125°C, enabling stable DC-coupled amplification in multiplexed data-acquisition systems. The 75 mA output drive capability allows direct interfacing with 2-kΩ loads while maintaining rail-to-rail swing within 25 mV at 2.7 V supply.

Key Specifications

Pinout & Package

The TLV9152IDGKR is housed in an 8-pin VSSOP package (DGK), measuring 3.00 mm × 3.00 mm with 0.65-mm pitch. This thermally enhanced, surface-mount package supports automated assembly and offers improved board-level thermal resistance (R_θJB = 98.2°C/W) versus SOIC-8.

FAQ

What is the maximum capacitive load the TLV9152IDGKR can drive stably?

The TLV9152IDGKR is specified to drive up to 1000 pF capacitively without oscillation, as confirmed in the Electrical Characteristics table under "Capacitive load drive." This capability enables direct connection to ADC input capacitors or long PCB traces in data-acquisition modules without requiring isolation resistors. Stability is maintained across its full 2.7–16 V supply range and –40°C to 125°C operating temperature, making TLV9152IDGKR suitable for ruggedized industrial sensor nodes where layout constraints limit decoupling options.

Does TLV9152IDGKR include shutdown functionality?

No, TLV9152IDGKR does not include shutdown functionality. The VSSOP-8 (DGK) package variant lacks SHDN pins; shutdown is only available in the X2QFN-10 (RUG) variant (TLV9152S). The TLV9152IDGKR pinout contains only power, input, and output terminals for both channels - eight pins total, with no dedicated control lines. Therefore, TLV9152IDGKR operates continuously when powered, and power gating must be implemented externally if low-quiescent operation is required between measurements.

What is the typical output voltage swing of TLV9152IDGKR at 3.3-V supply?

At 3.3-V supply (V+ = 3.3 V, V− = 0 V), TLV9152IDGKR delivers a typical output swing of 5–12 mV from each rail into a 10-kΩ load, per Electrical Characteristics Table 6.7. This rail-to-rail performance ensures >3.25 V of usable output range - critical for maximizing resolution when driving 12-bit ADCs with 3.3-V references. The specification is characterized across –40°C to 125°C, confirming consistent behavior in temperature-variable environments like factory automation cabinets.

How does TLV9152IDGKR perform in EMI-prone environments such as motor drives?

TLV9152IDGKR integrates EMI/RFI filters on both input pins, delivering >40 dB rejection at 900 MHz as shown in Figure 6-41 of the datasheet. In motor drive applications, this suppresses coupling from PWM switching noise (typically 10–20 kHz fundamental with harmonics to 100 MHz), preventing erroneous offset shifts or oscillation in current-sense amplifiers. Unlike standard op amps, TLV9152IDGKR requires no external RC filters for basic immunity - reducing BOM count and PCB area in compact inverter control boards.

Is TLV9152IDGKR pin-compatible with other dual op amps in VSSOP-8?

TLV9152IDGKR follows the industry-standard dual op amp pinout for VSSOP-8: Pin 1 = OUT A, Pin 2 = IN− A, Pin 3 = IN+ A, Pin 4 = V−, Pin 5 = IN+ B, Pin 6 = IN− B, Pin 7 = OUT B, Pin 8 = V+. This matches the pin mapping of OPA2313, OPA2314, and LMV722 - enabling drop-in replacement in many designs. However, differences in quiescent current, noise, and CMRR mean electrical validation is required before substitution, especially in precision or high-speed applications where TLV9152IDGKR's 4.5-MHz GBW and 10.5-nV/√Hz noise provide distinct advantages.
