Texas Instruments OPA4364AIDG4

Overview

OPA4364AIDG4 from Texas Instruments is a quad, rail-to-rail input/output, CMOS operational amplifier optimized for 1.8-V to 5.5-V single-supply operation. It delivers 7-MHz gain-bandwidth, 5-V/µs slew rate, 90-dB typical CMRR, and 750-µA/channel quiescent current - enabling precision signal conditioning in battery-powered sensor interfaces and portable data acquisition systems.

For engineers reviewing the OPA4364AIDG4 datasheet, OPA4364AIDG4 pinout, OPA4364AIDG4 application, or OPA4364AIDG4 equivalent, key selection criteria include its rail-to-rail I/O swing within 10 mV of rails, low 500-µV max input offset, 17-nV/√Hz input voltage noise density at 10 kHz, and guaranteed operation from –40°C to +125°C.

Technical Context

The OPA4364AIDG4 employs a complementary CMOS input stage that eliminates crossover distortion, ensuring monotonic common-mode response and high differential linearity when driving SAR or delta-sigma ADCs. Its unity-gain stable architecture supports direct connection to high-impedance sources without phase reversal.

Designed for single-supply systems, it accepts input common-mode voltages from (V–) – 0.1 V to (V+) + 0.1 V and delivers output swing to within 10 mV of both supply rails under 10-kΩ load. The device draws only 750 µA per channel at 5.5 V and features no shutdown function - distinguishing it from the OPA363 family.

FAQ

What is the maximum operating supply voltage for OPA4364AIDG4?

The OPA4364AIDG4 supports a maximum supply voltage of 5.5 V across the V+ to V– terminals. This rating applies to both single-supply (e.g., V+ = 5.5 V, V– = 0 V) and split-supply (e.g., V+ = ±2.75 V) configurations. Exceeding 5.5 V risks permanent damage, as confirmed in the Absolute Maximum Ratings table of the SBOS259F datasheet. Always maintain proper decoupling at the V+ pin when operating near this limit.

Does OPA4364AIDG4 include a shutdown pin?

No, OPA4364AIDG4 does not include a shutdown pin. Unlike the OPA363 family (which adds an enable pin), the OPA4364 series is a fixed-function quad op-amp with no power-management control. All four amplifiers operate continuously when powered. If low-power standby is required, external FET switching of the V+ rail or selection of the OPA4363 variant (with shutdown) is necessary - OPA4364AIDG4 itself has no logic-controlled disable capability.

What is the input common-mode voltage range for OPA4364AIDG4?

The input common-mode voltage range for OPA4364AIDG4 extends from (V–) – 0.1 V to (V+) + 0.1 V, as specified in the Electrical Characteristics table. At 5-V supply, this means inputs can swing from –0.1 V to 5.1 V - fully encompassing both rails. This rail-to-rail input capability enables direct interfacing with sensors whose output may exceed the supply, provided input current is limited to ±10 mA per pin per Absolute Maximum Ratings.

Can OPA4364AIDG4 drive capacitive loads?

Yes, OPA4364AIDG4 is specified to drive capacitive loads up to 100 pF while maintaining stability and 0.1% settling in ≤1 µs, per the datasheet's tS parameter. For loads exceeding 100 pF, external isolation resistance (e.g., 10–50 Ω in series with the output) is recommended to prevent peaking or oscillation. The device is unity-gain stable and does not require internal compensation, but layout parasitics must be minimized in high-frequency applications.

What package type is used for OPA4364AIDG4?

OPA4364AIDG4 uses the 14-pin SOIC (D package) with nominal dimensions of 8.65 mm × 3.91 mm. This surface-mount package is RoHS-compliant, tape-and-reel deliverable, and compatible with standard reflow profiles. The "DG4" suffix in the part number explicitly denotes the SOIC-D package - distinct from the TSSOP (PW) variant OPA4364AIPW, which uses a 5.00 mm × 4.40 mm footprint.
