Product details
Overview
OPA4364AIPWTG4 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, ±10-pA input bias current, and 500-µV maximum input offset voltage - enabling precision signal conditioning in battery-powered sensor interfaces and data acquisition systems.
For engineers reviewing the OPA4364AIPWTG4 datasheet, OPA4364AIPWTG4 pinout, OPA4364AIPWTG4 application, or OPA4364AIPWTG4 equivalent, key selection criteria include its rail-to-rail I/O swing within 10 mV of rails, low 750-µA/channel quiescent current at 5.5 V, wide –40°C to +125°C temperature range, and compatibility with electret microphone preamplifier topologies requiring high CMRR and low noise.
Technical Context
The OPA4364AIPWTG4 implements a complementary CMOS input stage that eliminates crossover distortion, ensuring monotonic common-mode response and preserving differential linearity when driving SAR and delta-sigma ADCs. Its unity-gain stable architecture supports active filter, transimpedance, and instrumentation configurations without external compensation.
It operates across 1.8–5.5 V supply range with input common-mode voltage extending 0.1 V beyond both rails and output swing limited only by 10–20 mV from each rail under 10-kΩ load. No shutdown function is present - distinguishing it from the OPA363 family and confirming its role as a continuous-operation precision amplifier.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | 1.8 V to 5.5 V single supply - enables direct interface with Li-ion, coin-cell, and 3.3-V/5-V logic systems without level-shifting. |
| Gain-Bandwidth Product | 7 MHz - supports stable closed-loop gain ≥10 up to ~700 kHz, suitable for anti-aliasing and reconstruction filters. |
| Slew Rate | 5 V/µs - ensures ≤1.5 µs settling to 0.01% for 4-V steps, critical for fast data acquisition front-ends. |
| Input Offset Voltage | ≤500 µV (max) - reduces DC error in precision sensor amplification, e.g., bridge-based pressure or temperature sensing. |
| CMRR | 90 dB (typ), 74 dB (min) - maintains accuracy in noisy industrial environments where common-mode interference exceeds 100 mV. |
| Quiescent Current | 750 µA per channel (max) at 5.5 V - allows four-channel operation below 3 mA total, ideal for always-on portable instrumentation. |
| Input Bias Current | ±10 pA (max) - minimizes voltage error across high-impedance sources like piezoelectric sensors or pH electrodes. |
Pinout & Package
TSSOP-14 package (PW), 5.00 mm × 4.40 mm body size, 0.65-mm lead pitch, exposed pad optional - compatible with standard surface-mount reflow profiles and space-constrained PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | VOUT A | Amplifier A output - drives downstream ADC input or feedback network; rail-to-rail swing supports full-scale utilization. |
| 2 | –IN A | Inverting input, Channel A - used in inverting gain stages or transimpedance configurations with photodiodes. |
| 3 | +IN A | Noninverting input, Channel A - accepts high-impedance sensor signals directly; common-mode range includes both supplies. |
| 4 | V+ | Positive power supply - connects to main system rail (e.g., 3.3 V or 5 V); decoupling capacitor required at pin. |
| 5 | +IN B | Noninverting input, Channel B - electrically isolated from Channel A; enables dual-sensor differential measurement. |
| 6 | –IN B | Inverting input, Channel B - paired with Pin 5 for matched gain configuration; layout symmetry recommended. |
| 7 | VOUT B | Amplifier B output - independent output node; no internal crosstalk with Channels C/D per channel separation >100 dB @ 1 kHz. |
| 8 | VOUT C | Amplifier C output - identical electrical specs to Pins 1 and 7; supports three-channel simultaneous sampling. |
| 9 | –IN C | Inverting input, Channel C - supports multi-channel active filtering or programmable gain amplifier (PGA) front-end. |
| 10 | +IN C | Noninverting input, Channel C - referenced to same V– as all channels; enables true rail-to-rail input common-mode range. |
| 11 | V– | Negative power supply - tied to ground in single-supply use; must be low-impedance return path for all four amplifiers. |
| 12 | +IN D | Noninverting input, Channel D - completes quad-channel set; usable for reference buffering or auxiliary signal path. |
| 13 | –IN D | Inverting input, Channel D - matches input capacitance (2 pF diff / 3 pF cm) across all channels for consistent AC response. |
| 14 | VOUT D | Amplifier D output - fully specified for 10-kΩ load and 100-pF capacitive drive; supports direct connection to ADC sample capacitor. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Output swings within 10 mV of V+ and V–; input accepts signals 0.1 V beyond either rail - maximizes dynamic range in low-voltage systems. |
| No phase reversal | Guaranteed monotonic output behavior during input overdrive - prevents latch-up or erroneous ADC codes in transient conditions. |
| High CMRR (90 dB) | Maintains accuracy despite power-supply ripple or EMI coupling on shared V+ or V– traces - critical for mixed-signal PCBs. |
| Low input bias current (±10 pA) | Enables use with MΩ-range source impedances without significant DC error - essential for electrochemical and piezoelectric sensors. |
| Unity-gain stable | Operates reliably with gain = 1 without external compensation - simplifies design of buffer, voltage follower, and active filter stages. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA4340UA | Higher 10-MHz GBW, 8-V/µs slew rate, but 1.2-mV max VOS and 1.6-mA/channel IQ at 5.5 V. | Better for higher-speed filtering; less suitable for ultra-low-power or precision DC-coupled sensor apps. | Choose OPA4340UA when bandwidth >7 MHz is required and power budget allows >2× higher IQ. |
| TLV9064IPWR | Lower 5.5-V/µs slew rate, 5.5-MHz GBW, but 0.3-mV max VOS and 560-µA/channel IQ at 5.5 V. | Optimized for lower-offset, lower-power trade-off; not specified for 1.8-V operation. | Choose TLV9064IPWR when sub-mV offset is critical and minimum supply is 2.7 V. |
Compared with OPA4364AIPWTG4, OPA4340UA offers higher speed at higher power cost, while TLV9064IPWR trades bandwidth for lower offset and quiescent current - making OPA4364AIPWTG4 the balanced choice for 1.8-V–5.5-V, 7-MHz, rail-to-rail precision applications.

FAQ
What is the operating temperature range for OPA4364AIPWTG4?
The OPA4364AIPWTG4 is fully specified from –40°C to +125°C ambient temperature. This extended industrial range ensures reliable performance in harsh environments such as factory automation controllers, automotive cabin modules, and outdoor sensor nodes - with all key parameters (offset, CMRR, GBW, IQ) guaranteed across the full span.
Does OPA4364AIPWTG4 include a shutdown pin?
No, OPA4364AIPWTG4 does not feature a shutdown function. Unlike the OPA363 family (which includes an enable pin), the OPA4364AIPWTG4 is a continuous-operation amplifier. All four channels remain active whenever powered - confirmed by absence of Enable pins in its TSSOP-14 pinout and omission of shutdown specifications in its Electrical Characteristics table.
Can OPA4364AIPWTG4 drive capacitive loads?
Yes, OPA4364AIPWTG4 is characterized for capacitive load drive up to 100 pF with stable step response (≤10% overshoot). For loads exceeding 100 pF, external isolation resistance (e.g., 10–50 Ω in series with output) is recommended. The device's unity-gain stability and 5-V/µs slew rate ensure robust performance into typical ADC input capacitances and PCB trace capacitance.
What is the maximum supply voltage for OPA4364AIPWTG4?
The absolute maximum supply voltage for OPA4364AIPWTG4 is 5.5 V across V+ to V–. The recommended operating range is 1.8 V to 5.5 V, with full parameter guarantees at 5.5 V - including 750-µA/channel max quiescent current and 7-MHz gain-bandwidth. Operation above 5.5 V risks permanent damage per Absolute Maximum Ratings.
Is OPA4364AIPWTG4 pin-compatible with other OPA4364 variants?
Yes, OPA4364AIPWTG4 (TSSOP-14, PW package) shares identical pinout and electrical specifications with OPA4364AIDR (SOIC-14, D package). Both comply with the same datasheet SBOS259F Rev F and support interchangeable placement in designs where board space or thermal requirements dictate package selection.
