Product details
Overview
MIC7300YM5-TR from Microchip Technology is a rail-to-rail input/output CMOS operational amplifier in SOT-23-5 package, delivering >80 mA peak sink/source drive at 5V supply, supporting 6000 pF capacitive loads at 10V, and specified across 2.2V–10V supply range for battery-powered instrumentation and USB peripherals.
For engineers reviewing the MIC7300YM5-TR datasheet, MIC7300YM5-TR pinout, MIC7300YM5-TR application, or MIC7300YM5-TR equivalent, this page provides verified electrical specs, thermal limits, output swing behavior under varying loads, and real-world design guidance for high-drive single-supply op-amp selection.
Technical Context
The MIC7300YM5-TR implements a CMOS input stage with >1 TΩ input resistance and sub-pA bias current, enabling precision sensing in high-impedance circuits. Its rail-to-rail input extends 300 mV beyond supply rails, and output swings to within 0.3 mV of both rails under 100 kΩ load at 5V.
It features 500 kHz gain-bandwidth product and 0.5 V/μs slew rate, with phase margin maintained at ≥40° even when driving up to 6000 pF at 10V supply - a key differentiator for stability-critical buffer and driver applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.2V to 10V - supports direct operation from Li-ion (3.7V), USB (5V), or dual-cell alkaline (3V) without regulation. |
| Output Drive Capability | >80 mA peak sink/source at 5V - drives low-impedance loads (e.g., 600Ω) while maintaining rail-to-rail swing. |
| Capacitive Load Drive | Up to 6000 pF at 10V supply - enables stable buffering of ADC inputs, LCD bias lines, or long PCB traces without external compensation. |
| Input Offset Voltage | 1.0 mV typical (2.2V–10V) - ensures <1 LSB error in 12-bit systems with gain ≤10. |
| THD @ 1 kHz | 0.01% at 10V, 2 kΩ load - meets audio-grade signal integrity requirements in portable DAC buffers. |
| Junction Temp Range | –40°C to +85°C - qualified for industrial and extended-temperature embedded instrumentation. |
| Thermal Resistance θJA | 260°C/W (SOT-23-5) - requires derating above ~20 mW dissipation in still-air environments. |
Pinout & Package
SOT-23-5 package (3.0 mm × 1.7 mm × 1.3 mm height), surface-mount, RoHS-compliant, marked "A17" on top face per DS20006305A-page 15.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | V+ | Positive supply terminal - accepts 2.2V–10V; must be decoupled with ≥0.1 μF ceramic near pin. |
| 2 | IN− | Inverting input - high-impedance node; sensitive to layout-induced leakage and noise coupling. |
| 3 | IN+ | Noninverting input - rail-to-rail common-mode range (–0.3V to V+ + 0.3V) enables direct sensor interfacing. |
| 4 | OUT | Amplifier output - capable of sourcing/sinking >80 mA; output resistance ≈12 Ω at 5V (per Fig 4-2). |
| 5 | V− | Negative supply or ground reference - connects to system GND in single-supply configurations. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Input operates –0.3V to V+ + 0.3V; output swings to within 0.3 mV of rails at 100 kΩ - eliminates level-shifting in 3.3V/5V microcontroller interfaces. |
| High capacitive load drive | Stable with up to 6000 pF at 10V (phase margin ≥40°) - removes need for isolation resistors in LCD column drivers or SAR ADC sample-hold buffers. |
| Ultra-low input bias current | 0.5 pA typical - preserves signal integrity in photodiode transimpedance amps and high-value RC filter networks. |
| Low THD + Noise | 0.01% THD at 1 kHz, 37 nV/√Hz input voltage noise - suitable for precision audio line drivers and low-noise sensor signal chains. |
| Wide supply range | 2.2V–10V operation with full spec compliance at 2.2V, 3V, 5V, and 10V - simplifies BOM consolidation across multiple power domains. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-output rail-to-rail op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA365AIDBVR | Lower drive (45 mA), higher GBWP (50 MHz), higher supply current (4.2 mA), no 2.2V min spec. | Better for high-frequency filtering but unsuitable for >60 mA load or sub-3V battery operation. | Select OPA365AIDBVR only if bandwidth >1 MHz is required and load current <45 mA. |
| TS912IDT | Lower drive (40 mA), lower THD (0.003%), wider temp range (–40°C to +125°C), SOT-23-5 compatible. | Preferred for automotive-adjacent industrial sensors where extended temperature is critical but drive demand is moderate. | Choose TS912IDT when ambient exceeds +85°C or THD <0.005% is mandatory; avoid for >50 mA loads. |
Compared with OPA365AIDBVR and TS912IDT, the MIC7300YM5-TR uniquely balances high output current (>80 mA), ultra-low input bias (0.5 pA), and guaranteed operation down to 2.2V - making it optimal for space-constrained, battery-sensitive instrumentation where drive strength and precision coexist.

FAQ
What is the maximum capacitive load the MIC7300YM5-TR can drive stably?
The MIC7300YM5-TR can drive up to 6000 pF stably at 10V supply with ≥40° phase margin, as confirmed in Figure 2-3 and Section 4.4 of DS20006305A. At 5V, it supports ≥4500 pF; at 2.2V, ≥2500 pF. Stability is verified in unity-gain configuration - no external compensation required within these limits. Always verify layout parasitics when approaching max load values.
Does the MIC7300YM5-TR support true rail-to-rail input at 2.2V supply?
Yes. The MIC7300YM5-TR guarantees rail-to-rail input operation from –0.3V to V+ + 0.3V across its full supply range, including 2.2V. Per DC Characteristics (2.2V) table on DS20006305A-page 2, input common-mode voltage spans –0.3V to 2.5V (i.e., V+ + 0.3V), enabling direct connection to sensors or references operating near ground or supply rails.
What is the typical output resistance of the MIC7300YM5-TR?
The MIC7300YM5-TR exhibits symmetric sink/source output resistance of approximately 12 Ω at 5V supply, calculated from output swing data (e.g., 0.015V drop at 1.243 mA load per Equation 4-4, DS20006305A-page 11). This low resistance enables strong drive into 600Ω loads while maintaining <250 mV dropout - critical for precision buffer applications.
Can the MIC7300YM5-TR operate from a single 2.2V lithium coin cell?
Yes. The MIC7300YM5-TR is fully specified at 2.2V supply (DS20006305A-page 2–3), with guaranteed performance including 1.0 mV typical offset, 0.5 pA bias current, and >60 mA short-circuit current. Its 0.7 mA typical supply current at 2.2V enables multi-year operation in low-duty-cycle instrumentation powered by CR2032 cells.
Is the MIC7300YM5-TR pin-compatible with other SOT-23-5 op-amps like MCP6001 or LMV321?
No. While all use SOT-23-5 packaging, the MIC7300YM5-TR pinout (V+, IN−, IN+, OUT, V−) differs from industry-standard pinouts such as MCP6001 (V+, IN+, IN−, OUT, GND) and LMV321 (OUT, IN−, IN+, V+, GND). Substitution requires PCB layout revision - refer to Table 3-1 (DS20006305A-page 10) for exact terminal mapping.
