Product details
Overview
UPC277GR(5)-9LG-E1-A from Renesas Electronics is a dual operational amplifier optimized for single-supply operation with rail-to-rail input (V− to V+ − 1.4 V) and output swing down to GND, ±2 mV typical input offset voltage, 0.7–0.9 mA supply current, and 100,000 typical large-signal voltage gain - deployed in sensor signal conditioning circuits requiring low-voltage precision amplification.
For engineers reviewing the UPC277GR(5)-9LG-E1-A datasheet, UPC277GR(5)-9LG-E1-A pinout, UPC277GR(5)-9LG-E1-A application, or UPC277GR(5)-9LG-E1-A equivalent, key selection criteria include guaranteed ±3 mV max input offset voltage (DC-optimized variant), TSSOP-8 (5.72 mm) package compatibility, single-supply operation from +3 V to +30 V, and output sink/source capability up to 50 μA/40 mA under defined load conditions.
Technical Context
This bipolar-input dual op-amp uses a class-C push-pull output stage enabling true GND-level output swing and common-mode input range extending to V− (GND). Its internal frequency compensation ensures unity-gain stability without external components across its full operating voltage range.
The device implements PNP-input transistors yielding 14–60 nA input bias current (direction outward), supports split-supply (±1.5 V to ±15 V) or single-supply (V− = GND) configurations, and delivers 120 dB channel separation at 1–20 kHz - critical for dual-channel instrumentation where crosstalk must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Offset Voltage | ±2 mV (TYP.), ±3 mV (MAX) - enables DC-coupled sensor interfaces without external nulling circuitry |
| Supply Current | 0.7–0.9 mA - allows battery-powered portable instrumentation with multi-day operation |
| Output Voltage Swing | 0 V to V+ − 1.5 V (RL = 2 kΩ) - supports direct interfacing to 3.3 V or 5 V ADCs without level-shifting |
| Common-Mode Input Range | 0 V to V+ − 1.4 V - accepts signals referenced to GND in single-supply systems |
| Large Signal Voltage Gain | 50,000–100,000 - provides ≥94 dB open-loop gain for high-precision closed-loop configurations |
| Channel Separation | 120 dB @ 1–20 kHz - prevents inter-channel interference in dual-sensor monitoring |
| Operating Temperature | −40°C to +125°C - qualified for under-hood automotive and industrial control environments |
Pinout & Package
UPC277GR(5)-9LG-E1-A is housed in an 8-pin plastic TSSOP package (5.72 mm body width, 0.65 mm lead pitch), measuring 3.15 mm × 4.40 mm with 1.00 mm height and 0.25 mm thickness - reducing PCB area by 60% versus standard SOP-8.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Channel 1) | Accepts differential input signal; referenced to V− (GND) in single-supply mode |
| 2 | Non-Inverting Input (Channel 1) | Accepts reference or sensor signal; common-mode range extends to V− |
| 3 | Output (Channel 1) | Class-C push-pull stage drives loads down to GND; short-circuit protected |
| 4 | V− (Ground) | Power return node; also serves as common-mode reference for inputs and outputs |
| 5 | Non-Inverting Input (Channel 2) | Independent second channel input; identical electrical characteristics to Pin 2 |
| 6 | Inverting Input (Channel 2) | Independent second channel input; identical electrical characteristics to Pin 1 |
| 7 | Output (Channel 2) | Electrically isolated from Channel 1 output; 120 dB channel separation maintained |
| 8 | V+ | Positive supply rail; supports +3 V to +30 V single-supply or ±1.5 V to ±15 V dual-supply operation |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input common-mode range | Extends from V− (GND) to V+ − 1.4 V - eliminates need for input biasing networks in single-supply designs |
| GND-referenced output stage | Class-C push-pull architecture delivers true 0 V output - enables direct connection to microcontroller ADCs with VREF = GND |
| DC parameter selection grade | Guaranteed ±3 mV max input offset voltage - reduces calibration overhead in precision analog front-ends |
| Low quiescent current | 0.7–0.9 mA total supply current - supports always-on sensor nodes in energy-constrained applications |
| Robust ESD protection | Qualified per JESD22-A114 (2 kV HBM) - withstands handling and board assembly without additional protection diodes |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM358DR | Higher input offset voltage (±7 mV MAX), wider SOIC-8 package, no DC-parameter selection grade | Limited to cost-sensitive consumer applications; not recommended for precision sensor front-ends requiring <±5 mV offset | Select LM358DR only when budget constraints outweigh precision requirements and PCB space permits larger SOIC footprint |
| TLV2372IDR | Rail-to-rail I/O, CMOS input (0.5 pA bias current), but lower output drive (25 mA sink/source) and narrower temp range (−40°C to +125°C same) | Better for ultra-low-power battery devices; less suitable for driving 2 kΩ loads at full swing due to reduced output current | Choose TLV2372IDR when input bias current <1 pA is mandatory and load impedance exceeds 10 kΩ |
Compared with LM358DR and TLV2372IDR, UPC277GR(5)-9LG-E1-A uniquely combines guaranteed low-offset DC performance, bipolar-input robustness against EMI, and compact TSSOP-8 packaging - making it optimal for space-constrained industrial and automotive dual-channel analog signal chains where precision and reliability are co-prioritized.

FAQ
What is the maximum operating supply voltage for UPC277GR(5)-9LG-E1-A?
The absolute maximum voltage between V+ and V− pins of UPC277GR(5)-9LG-E1-A is +32 V. For reliable operation, the recommended single-supply range is +3 V to +30 V (V− = GND), or ±1.5 V to ±15 V in split-supply mode. Exceeding +30 V risks exceeding thermal limits even at room temperature due to power dissipation constraints specified in the datasheet's derating curves.
Does UPC277GR(5)-9LG-E1-A support rail-to-rail output swing?
UPC277GR(5)-9LG-E1-A provides rail-to-rail input capability (common-mode range from V− to V+ − 1.4 V), but its output swings from 0 V (GND) to V+ − 1.5 V under 2 kΩ load - not fully to V+. This GND-referenced output is sufficient for interfacing with most 3.3 V or 5 V ADCs whose lower reference is tied to GND, eliminating need for negative supply rails.
What does the "(5)" suffix in UPC277GR(5)-9LG-E1-A signify?
The "(5)" in UPC277GR(5)-9LG-E1-A denotes the DC parameter selection grade: it guarantees tighter limits on key DC parameters - specifically ±3 mV maximum input offset voltage (vs. ±7 mV for non-(5) variants) and 14–60 nA input bias current (vs. 14–250 nA). This grade is selected for applications requiring higher initial accuracy without post-manufacturing calibration.
Is UPC277GR(5)-9LG-E1-A RoHS-compliant and lead-free?
Yes, UPC277GR(5)-9LG-E1-A is Pb-free: the product documentation explicitly states "This product does not contain Pb in the external electrode and other parts." It complies with EU RoHS Directive requirements, and Renesas confirms its environmental compliance through material declarations and process controls documented in their quality assurance system.
Can unused op-amp channels in UPC277GR(5)-9LG-E1-A be left floating?
No - unused channels in UPC277GR(5)-9LG-E1-A must be properly terminated to avoid instability or increased supply current. The datasheet recommends connecting the inverting input to the output (unity-gain buffer configuration) and the non-inverting input to a stable voltage within the common-mode range (e.g., midpoint of V+ and V−). Leaving inputs unconnected may cause phase reversal or oscillation due to internal transistor biasing effects.
