Texas Instruments OPA364IDBVT

Overview

OPA364IDBVT from Texas Instruments is a single, rail-to-rail input/output CMOS operational amplifier optimized for low-voltage, single-supply operation (1.8 V to 5.5 V). It delivers 7 MHz gain-bandwidth, 5 V/µs slew rate, and 90 dB typical CMRR, with ±10 mV output swing from rails at 10 kΩ load - making it suitable for electret microphone preamplification, sensor signal conditioning, and data acquisition in battery-powered systems.

For engineers reviewing the OPA364IDBVT datasheet, OPA364IDBVT pinout, OPA364IDBVT application, or OPA364IDBVT equivalent, key selection considerations include its 500 µV maximum input offset voltage, 750 µA maximum quiescent current per channel, shutdown-free 5-pin SOT-23 package, and guaranteed operation from –40°C to +125°C.

Technical Context

The OPA364IDBVT uses a complementary CMOS input stage that eliminates crossover distortion, enabling high common-mode rejection (90 dB typ.) across the full input range - including both supply rails - without degrading THD or differential linearity when driving ADCs. Its unity-gain stable architecture supports precision active filtering and low-noise amplification with 17 nV/√Hz input voltage noise density at 10 kHz.

No internal shutdown function is present - unlike the pin-compatible OPA363 family - so the device operates continuously with no enable control logic. The 5-pin SOT-23 (DBV) package places all critical terminals (V+, V–, IN+, IN–, VOUT) on standard 0.95 mm pitch, supporting compact PCB layouts in space-constrained portable electronics.

Key Specifications

Pinout & Package

OPA364IDBVT is housed in a 5-pin SOT-23 (DBV) package measuring 2.60 mm × 1.60 mm × 1.15 mm, with gull-wing leads and exposed pad not connected internally. Thermal resistance R_θJA is 182.7°C/W, requiring minimal copper area for industrial-temperature operation.

FAQ

What is the maximum supply voltage for the OPA364IDBVT?

The OPA364IDBVT supports a maximum supply voltage of 5.5 V across V+ and V– pins. Operation above this rating risks permanent damage, as specified in the Absolute Maximum Ratings table. For reliable long-term performance, TI recommends staying within 1.8 V to 5.5 V, with 5.0 V being the typical upper limit in production designs using 5 V rails.

Does the OPA364IDBVT have a shutdown pin?

No, the OPA364IDBVT does not include a shutdown pin. It is a 5-pin device with fixed operation: pins 1–5 are VOUT, V–, +IN, –IN, and V+. In contrast, the pin-compatible OPA363IDBVT uses a 6-pin SOT-23 package with pin 5 dedicated to shutdown control. The OPA364IDBVT draws 750 µA continuously and cannot be disabled.

Can the OPA364IDBVT drive a 100-pF capacitive load stably?

Yes, the OPA364IDBVT is unity-gain stable and characterized for CL = 100 pF in the datasheet's Electrical Characteristics table. Its small-signal step response (Figure 19) shows <5% overshoot under these conditions, confirming stable operation without external isolation resistors - provided the feedback network is properly laid out with minimal parasitic capacitance at the inverting input.

What is the input common-mode voltage range of the OPA364IDBVT?

The OPA364IDBVT features rail-to-rail input capability: its input common-mode voltage range extends from (V–) – 0.1 V to (V+) + 0.1 V. This allows direct connection to signals referenced to ground or V+ in single-supply systems, and supports true DC-coupled operation across the full supply range - a key enabler for precision sensor interfaces and active filters.

Is the OPA364IDBVT suitable for automotive applications?

The OPA364IDBVT is specified for operation from –40°C to +125°C and meets industrial reliability standards, but it is not AEC-Q200 qualified. It may be used in non-safety-critical automotive subsystems (e.g., cabin climate sensors, infotainment audio stages) where customer qualification is performed. For ASIL-B/C applications, TI recommends AEC-Q100 qualified alternatives such as the OPA2333-Q1.
