Product details
Overview
UPC277G2(3)-E2-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 1.2 mA maximum supply current at +5 V. It serves as a general-purpose signal conditioning IC in battery-powered sensor interfaces and portable analog front-ends.
For engineers reviewing the UPC277G2(3)-E2-A datasheet, UPC277G2(3)-E2-A pinout, UPC277G2(3)-E2-A application, or UPC277G2(3)-E2-A equivalent, this page delivers verified electrical parameters, TSSOP-8 package details, thermal derating behavior above 44°C, and two validated alternative op-amps for design continuity.
Technical Context
The UPC277G2(3)-E2-A implements a bipolar-input, class-C push-pull output stage enabling true GND-level output sinking and low-voltage operation from +3 V to +30 V. Its PNP first-stage input bias current flows out of the pins (14–250 nA), and internal frequency compensation ensures unity-gain stability without external components.
It supports both single-supply (V− = GND) and split-supply (±1.5 V to ±15 V) configurations, with common-mode input range extending to V− and output swing reaching within 1.5 V of V+. Channel separation exceeds 120 dB from 1 kHz to 20 kHz, minimizing crosstalk in dual-channel signal paths.

Pinout & Package
UPC277G2(3)-E2-A is housed in an 8-pin plastic TSSOP (5.72 mm × 4.4 mm, 0.65 mm pitch) with exposed pad not present. Pin 1 is located at the take-up side of the embossed tape.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Channel 1) | Accepts feedback or signal inversion node; input bias current flows out (PNP input stage) |
| 2 | Non-Inverting Input (Channel 1) | Reference or signal input node; common-mode range includes V− (GND) |
| 3 | Output (Channel 1) | Class-C push-pull output capable of sourcing 40 mA and sinking 20 mA into 2 kΩ load |
| 4 | V− (Ground) | Power return for single-supply operation; also serves as common-mode reference |
| 5 | Inverting Input (Channel 2) | Dual-channel symmetry enables independent signal conditioning paths on one die |
| 6 | Non-Inverting Input (Channel 2) | Matches Channel 1 electrical characteristics; supports matched dual-sensor amplification |
| 7 | Output (Channel 2) | Electrically isolated from Channel 1 output; channel separation >120 dB prevents intermodulation |
| 8 | V+ | Positive supply rail; absolute max rating +32 V allows transient overvoltage tolerance |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input capability | Common-mode range extends to V− (GND), eliminating need for level-shifting in single-supply sensor interfaces |

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 (±3 mV typ.), lower CMRR (70 dB min), no guaranteed operation below +3 V | Less suitable for low-voltage sensor nodes requiring <±2 mV offset stability | Select when cost sensitivity outweighs precision and low-voltage performance |
| TLV2372IDR | CMOS input (pA bias), rail-to-rail output only, 1.8 V min supply, higher quiescent current (1.4 mA) | Better for ultra-low-power, high-impedance sources but lacks bipolar input ruggedness | Select when interfacing with MEMS sensors or high-Z potentiometers |
Compared with LM358DR and TLV2372IDR, UPC277G2(3)-E2-A uniquely balances low input offset, bipolar input ruggedness, and true single-supply rail-to-rail input operation - making it optimal for industrial analog front-ends where precision, supply flexibility, and ESD tolerance are jointly critical.

FAQ
What is the maximum operating ambient temperature for UPC277G2(3)-E2-A?
The UPC277G2(3)-E2-A has a maximum operating ambient temperature of +85°C. Its total power dissipation must be derated by −5.5 mW/°C above +44°C to remain within safe thermal limits, based on a junction-to-ambient thermal resistance of 183°C/W. This derating ensures reliability in enclosed industrial enclosures without forced airflow.
Does UPC277G2(3)-E2-A support rail-to-rail output?
UPC277G2(3)-E2-A provides rail-to-rail input (down to V−) but not full rail-to-rail output: its output swings from 0 V to V+ − 1.5 V under 2 kΩ load. This GND-referenced output capability enables direct interfacing with ADCs and logic circuits in single-supply systems, though headroom must be reserved for the 1.5 V saturation margin.
Is UPC277G2(3)-E2-A pin-compatible with other Renesas dual op-amps like μPC358GR-9LG?
Yes, UPC277G2(3)-E2-A shares the same 8-pin TSSOP (5.72 mm) package and identical pinout as μPC358GR-9LG-E2-A and μPC1251GR-9LG-E2-A. All three devices use Pin 1 at the take-up side, matching footprint and solder reflow profiles - enabling drop-in replacement where electrical specifications align with system requirements.
What is the input bias current direction and magnitude for UPC277G2(3)-E2-A?
The UPC277G2(3)-E2-A uses a PNP-input stage, so input bias current flows *out* of both inverting and non-inverting terminals. Typical input bias current is 14 nA at +5 V supply, rising to 250 nA maximum across temperature and voltage extremes. This outward flow must be accommodated in high-impedance feedback networks to avoid offset voltage errors.
Can UPC277G2(3)-E2-A operate from a ±15 V split supply?
Yes, UPC277G2(3)-E2-A supports split-supply operation from ±1.5 V to ±15 V. In this configuration, its common-mode input range spans ±13.5 V and output swing reaches within 1.5 V of each rail. This dual-supply mode is commonly used in test equipment and audio line drivers where symmetric signal handling is required.
