Product details
Overview
AZV358GTR-G1 from Diodes Incorporated is a dual rail-to-rail output operational amplifier designed for low-voltage signal conditioning in battery-powered systems. It operates from 2.7V to 5.5V, delivers 1MHz gain-bandwidth product and 1V/µs slew rate, draws only 210µA supply current at 5V, and supports industrial temperature range (–40°C to +85°C). Its bipolar input stage enables low input offset voltage (1.7mV typ) and high output drive capability (±60mA short-circuit current).
For engineers reviewing the AZV358GTR-G1 datasheet, AZV358GTR-G1 pinout, AZV358GTR-G1 application, or AZV358GTR-G1 equivalent, this page provides verified technical context, package-specific pin mapping, real-world use cases in portable electronics, and validated alternative options for legacy design continuity.
Technical Context
The AZV358GTR-G1 integrates two independent op-amps on a single BiCMOS die, with bipolar input transistors for low noise and offset, and CMOS output stages enabling rail-to-rail swing under 10kΩ load (VOH ≥ VCC – 10mV, VOL ≤ VEE + 65mV). Input common-mode range extends to –0.1V, supporting ground-referenced sensing.
It achieves stable unity-gain operation with ≥60° phase margin across capacitive loads up to 1000pF and resistive loads down to 620Ω. The device exhibits no crossover distortion and maintains 50dB CMRR over its full input common-mode range, making it suitable for precision DC-coupled amplification in mixed-signal front-ends.
Key Specifications

Applications
| Active Filter Design | Portable Audio Signal Chain |
|---|---|
Use Scenario: Second-order Sallen-Key low-pass filter for anti-aliasing before 100ksps ADC in handheld test equipment. IC Role / Device Role / Timing Role: Dual op-amp implements unity-gain buffer and filter integrator; one section buffers sensor output, the other configures frequency-selective feedback. Use Value: 1MHz GBW ensures filter cutoff accuracy within ±2% at 100kHz, while rail-to-rail swing preserves 3.0Vpp dynamic range from 3.3V supply. |
Use Scenario: Line-level preamplifier and headphone driver in Bluetooth earbud charging case with integrated diagnostics. IC Role / Device Role / Timing Role: One amplifier conditions microphone bias voltage; the other drives 16Ω headphones with 0dB gain and DC-blocking cap. Use Value: 1V/µs slew rate prevents clipping on 1kHz tone bursts; 60mA output sink/source supports 150mW into 16Ω without external boost. |
| Battery Voltage Monitor | Low-Power Sensor Interface |
Use Scenario: Precision resistor-divider scaling and buffering of Li-ion cell voltage (2.7–4.2V) for fuel gauge IC input. IC Role / Device Role / Timing Role: Non-inverting amplifier with 0.5× gain and unity-gain buffer isolates divider from ADC sampling transient. Use Value: 1.7mV offset contributes <0.04% error at 4.2V full scale; 210µA quiescent current adds <0.1% drain to 10µA sleep-mode budget. |
Use Scenario: Amplification of 10mV full-scale thermopile output in wearable temperature patch with 3.3V coin cell supply. IC Role / Device Role / Timing Role: Instrumentation-grade front-end: first amp configures differential gain, second provides rail-to-rail output to 12-bit ADC. Use Value: Bipolar input stage achieves 11nA bias current, minimizing voltage drop across 100kΩ thermopile source impedance. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual low-voltage rail-to-rail output operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV358DR | Higher supply current (240µA vs. 210µA), wider VCM (–0.1V to VCC+0.1V), same GBW/slew rate. | Supports slightly extended input range but lacks BiCMOS noise advantage; not qualified for automotive PPAP. | Preferred for cost-sensitive consumer designs where 30µA extra quiescent current is acceptable and AEC-Q100 is not required. |
| TSV912IDT | Lower input offset (1.5mV typ), higher GBW (8MHz), but 500µA supply current and narrower rail-to-rail swing (VOL = 100mV). | Enables faster settling in active filters but consumes >2× power; unsuitable for sub-500µA battery budgets. | Select when bandwidth >1MHz is mandatory and system power budget exceeds 1mA; avoid in coin-cell applications. |
Compared with AZV358GTR-G1, LMV358DR trades minor power penalty for broader availability and longer lifecycle, while TSV912IDT prioritizes speed over efficiency-making AZV358GTR-G1 optimal for balanced performance in space- and energy-constrained portable systems.

FAQ
Is AZV358GTR-G1 still in production?
No-AZV358GTR-G1 is officially obsolete and discontinued by Diodes Incorporated as of August 2024. Aetrix Electronics holds final-buy inventory and offers lifecycle support including last-time procurement, cross-reference guidance, and engineering consultation for migration to LMV358-based designs.
What is the correct replacement part recommended by Diodes?
Diodes explicitly recommends LMV358 as the functional replacement for AZV358, citing compatibility in pinout, electrical specifications, and package options. LMV358 maintains identical SOIC-8/TSSOP-8/MSOP-8 footprints and matches key parameters including 1MHz GBW, 1V/µs slew rate, and rail-to-rail output swing.
Can AZV358GTR-G1 operate from a 2.5V supply?
No-AZV358GTR-G1 has a minimum rated supply voltage of 2.7V per datasheet Absolute Maximum Ratings and Recommended Operating Conditions. Operation below 2.7V is not characterized, and parameters like CMRR, PSRR, and output swing are not guaranteed outside the 2.7–5.5V range.
Does AZV358GTR-G1 meet AEC-Q100 automotive qualification?
No-AZV358GTR-G1 is not AEC-Q100 qualified. The datasheet explicitly states that automotive-grade variants require specific change control, PPAP capability, and IATF 16949 manufacturing; no such version was released for AZV358. For automotive use, Diodes recommends LMV358-Q1 or AP358Q.
