Product details
Overview
UPC277GR(20)-9LG-E1-A from Renesas Electronics is a dual operational amplifier designed for single-supply operation with rail-to-rail input (V− to V+ − 1.5 V) and output swing down to GND, featuring ±2 mV typical input offset voltage, 100,000 typical large-signal voltage gain, and 0.7–1.2 mA supply current at +5 V. It serves as a precision signal conditioning IC in battery-powered sensor interfaces and low-voltage analog front-ends.
For engineers reviewing the UPC277GR(20)-9LG-E1-A datasheet, UPC277GR(20)-9LG-E1-A pinout, UPC277GR(20)-9LG-E1-A application, or UPC277GR(20)-9LG-E1-A equivalent, key selection criteria include guaranteed input offset voltage ≤±7 mV over temperature, output sink/source capability up to 20 mA/40 mA, and TSSOP-8 (5.72 mm) package compatibility with high-density PCB layouts.
Technical Context
This bipolar-input dual op-amp uses a class-C push-pull output stage enabling true GND-level output swing and supports both single-supply (+3 V to +30 V) and split-supply (±1.5 V to ±15 V) configurations. Its PNP-input first stage delivers low input bias current (14–250 nA) and enables common-mode input down to V−.
The device integrates internal frequency compensation, output short-circuit protection, and exhibits 120 dB channel separation at 1–20 kHz. It operates across −40°C to +125°C ambient temperature with junction-to-ambient thermal resistance of 183°C/W in its 8-pin TSSOP package.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +3 V to +30 V (single), ±1.5 V to ±15 V (split): Enables direct integration into 3.3 V, 5 V, and 12 V systems without level-shifting. |
| Input Offset Voltage | ±2 mV (typ), ±7 mV (max): Supports DC-coupled amplification of millivolt-level sensor signals without significant baseline error. |
| Large Signal Voltage Gain | 25,000–100,000 (min–typ): Ensures stable closed-loop gain ≥100 with adequate margin for feedback accuracy. |
| Output Swing (RL = 2 kΩ) | 0 V to V+ − 1.5 V: Delivers full dynamic range to ADCs or downstream logic referenced to GND. |
| Supply Current per Channel | 0.7–1.2 mA (typ–max): Allows dual-channel operation within 2.5 mA total for ultra-low-power portable designs. |
| Common-Mode Input Range | V− to V+ − 1.5 V: Accepts inputs at GND in single-supply mode-critical for current-sense and level-shifting applications. |
| Output Sink/Source Current | 10–20 mA / 20–40 mA: Drives moderate loads like LED indicators, small relays, or 10 kΩ DAC reference buffers directly. |
Pinout & Package
UPC277GR(20)-9LG-E1-A is housed in an 8-pin plastic TSSOP package (5.72 mm × 4.4 mm, 0.65 mm pitch), optimized for space-constrained industrial and consumer PCBs. The package is Pb-free and compatible with standard IR reflow profiles (peak 260°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Channel 1) | Accepts differential input signals; biased internally to enable single-supply operation from GND. |
| 2 | Non-Inverting Input (Channel 1) | Reference node for unity-gain buffer or non-inverting amplifier configurations. |
| 3 | Output (Channel 1) | Class-C push-pull output capable of sourcing up to 40 mA and sinking up to 20 mA. |
| 4 | V− (GND) | Power ground reference; common return for both channels and all external circuitry. |
| 5 | Non-Inverting Input (Channel 2) | Independent input for second amplifier; shares same V− and V+ rails. |
| 6 | Inverting Input (Channel 2) | Second differential input pair; electrically isolated from Channel 1 except via shared supply rails. |
| 7 | Output (Channel 2) | Independent output stage with identical drive strength and swing characteristics as Pin 3. |
| 8 | V+ | Positive supply rail; supports up to +30 V or ±15 V; decoupling capacitor required near this pin. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input (V− to V+ − 1.5 V) | Enables accurate amplification of signals near GND in single-supply systems-no external level shifters needed. |
| GND-referenced output swing | Drives loads directly to 0 V, simplifying interface with microcontroller ADCs and digital comparators. |
| Low input offset voltage (±2 mV typ) | Reduces DC error in precision instrumentation paths, such as thermocouple or strain gauge amplifiers. |
| Internal frequency compensation | Guarantees stability with unity-gain feedback; no external compensation components required. |
| Output short-circuit protection | Prevents latch-up or permanent damage during accidental output shorts-supports robust field deployment. |

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 | Wider supply range (±16 V), higher input offset (±3 mV typ), no guaranteed GND-swing output. | Limited to applications where output need not reach 0 V; less suitable for 3.3 V ADC interfacing. | Choose LM358DR only when legacy design reuse or cost sensitivity outweighs rail-to-rail performance needs. |
| TLV2372IDR | Rail-to-rail I/O, lower supply current (550 µA/ch), but lower output drive (8 mA sink/source) and narrower temp range (−40°C to +125°C). | Better for ultra-low-power systems; insufficient for driving 10 kΩ loads at >2 V swing. | Select TLV2372IDR when power budget is <1 mW/channel and load impedance exceeds 20 kΩ. |
Compared with LM358DR and TLV2372IDR, UPC277GR(20)-9LG-E1-A uniquely balances GND-swing output, 20 mA sink capability, and −40°C to +125°C operation-making it optimal for industrial sensor nodes requiring robustness and precision without rail-to-rail input limitations.

FAQ
What is the maximum operating ambient temperature for UPC277GR(20)-9LG-E1-A?
The UPC277GR(20)-9LG-E1-A is rated for operation from −40°C to +125°C ambient temperature. This specification applies to the μPC1251GR-9LG variant family, which includes UPC277GR(20)-9LG-E1-A, and is validated per Renesas' Standard quality grade for industrial applications including machine tools and test equipment.
Does UPC277GR(20)-9LG-E1-A support true rail-to-rail input?
UPC277GR(20)-9LG-E1-A supports rail-to-rail input down to V− (GND) but not up to V+. Its common-mode input voltage range is specified as V− to V+ − 1.5 V at TA = 25°C, meaning it accepts inputs at GND but cannot reliably process signals within 1.5 V of V+ without degradation.
Is UPC277GR(20)-9LG-E1-A pin-compatible with other μPC1251 variants?
Yes, UPC277GR(20)-9LG-E1-A shares the same 8-pin TSSOP (5.72 mm) package and pinout as μPC1251GR-9LG-E1-A and μPC358GR-9LG-E1-A. All three variants use identical pin assignments for V+, V−, IN+/−, and OUT for both channels, enabling drop-in replacement within the same family.
What is the typical supply current consumption of UPC277GR(20)-9LG-E1-A at +5 V?
The typical supply current for UPC277GR(20)-9LG-E1-A is 0.7 mA per channel (1.4 mA total) at TA = 25°C and V+ = +5 V with no load. Maximum supply current is 1.2 mA per channel under worst-case conditions, making it suitable for low-power dual-amplifier applications.
Does UPC277GR(20)-9LG-E1-A include output short-circuit protection?
Yes, UPC277GR(20)-9LG-E1-A includes built-in output short-circuit protection, allowing indefinite short-circuit duration to V− (GND) without damage. However, short circuits to V+ must be avoided, as they may cause destruction due to excessive power dissipation.
