Product details
Overview
UPC277GR(20)-9LG-E2-A from Renesas Electronics is a dual operational amplifier optimized for single-supply operation with rail-to-rail input (V− to V+ − 1.5 V) and output swing down to GND, ±2 mV typical input offset voltage, 100,000 typical large-signal voltage gain, and 1.2 mA maximum supply current - deployed in sensor signal conditioning and portable audio front-ends.
For engineers reviewing the UPC277GR(20)-9LG-E2-A datasheet, UPC277GR(20)-9LG-E2-A pinout, UPC277GR(20)-9LG-E2-A application, or UPC277GR(20)-9LG-E2-A equivalent, key selection criteria include guaranteed low-voltage operation (down to +3 V), output short-circuit protection, TSSOP-8 package compatibility, and DC parameter selection grade suitability for precision analog sensing.
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 and features output short-circuit protection with indefinite duration capability under specified thermal limits. Channel separation exceeds 120 dB at 1–20 kHz, confirming high isolation between amplifiers in shared-package operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +3 V to +30 V (single supply); supports battery-powered systems down to 3 V without rail shifting. |
| Input Offset Voltage | ±2 mV (typ), ±7 mV (max) - enables accurate DC-coupled amplification in 12-bit ADC front-ends. |
| Large Signal Voltage Gain | 100,000 (typ), ≥25,000 (min) - ensures stable closed-loop gain control up to 80 dB at DC/low frequency. |
| Output Voltage Swing | 0 V to V+ − 1.5 V (RL = 2 kΩ) - allows full-scale signal utilization in single-supply microcontroller interfaces. |
| Common-Mode Input Range | V− to V+ − 1.5 V (typ) - accepts ground-referenced sensors without level-shifting circuitry. |
| Supply Current | 0.7–1.2 mA per amplifier - enables dual-channel analog signal processing in power-constrained IoT nodes. |
| Channel Separation | ≥120 dB (1–20 kHz) - prevents crosstalk in stereo audio or dual-sensor differential measurement paths. |
Pinout & Package
UPC277GR(20)-9LG-E2-A is housed in an 8-pin plastic TSSOP package (5.72 mm × 4.4 mm, 0.65 mm pitch), RoHS-compliant and Pb-free, with embossed tape packaging and Pin 1 located at the take-up side.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Amplifier 1) | Accepts feedback or inverted signal path; referenced to V− for single-supply biasing. |
| 2 | Non-Inverting Input (Amplifier 1) | Accepts reference or sensor signal; supports common-mode range down to V−. |
| 3 | Output (Amplifier 1) | Class C push-pull output capable of sinking to V− (GND) and sourcing to V+ − 1.5 V. |
| 4 | V− (Ground) | Power return node; serves as signal reference and output lower rail in single-supply mode. |
| 5 | Inverting Input (Amplifier 2) | Dedicated second channel input; electrically isolated from Channel 1 per datasheet channel separation spec. |
| 6 | Non-Inverting Input (Amplifier 2) | Independent second channel input; supports dual-sensor or stereo signal routing. |
| 7 | Output (Amplifier 2) | Second independent output with identical swing and drive capability as Pin 3. |
| 8 | V+ | Positive supply rail; supports up to +30 V; reverse polarity protection not integrated. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input (V−-referenced) | Enables direct interfacing with ground-referenced transducers without external bias networks. |
| GND-level output swing | Eliminates need for negative supply in single-ended output stages driving ADCs or comparators. |

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), wider SOIC-8 package (4.9 mm vs. 4.4 mm), no guaranteed GND-sinking output. | Limited to non-critical industrial controls; unsuitable for precision sensor interfaces requiring V−-level output. | Select LM358DR only when board space and output swing constraints are relaxed. |
| TLV2372IDR | Rail-to-rail I/O, lower ICC (120 μA/ch), but bipolar input replaced by CMOS - higher input impedance, lower drive strength. | Better for high-Z sources (e.g., pH electrodes); less suitable for driving 2 kΩ loads or fast settling. | Choose TLV2372IDR for ultra-low-power, high-impedance sensing; retain UPC277GR(20)-9LG-E2-A for robust output drive and bipolar noise performance. |
Compared with LM358DR and TLV2372IDR, UPC277GR(20)-9LG-E2-A uniquely balances GND-sinking output, bipolar low-noise input, and compact TSSOP-8 footprint - making it optimal for space-constrained, single-supply precision analog systems where output drive and DC accuracy are jointly critical.

FAQ
What is the operating temperature range for UPC277GR(20)-9LG-E2-A?
The UPC277GR(20)-9LG-E2-A is rated for an operating ambient temperature range of −40°C to +125°C, matching the μPC1251GR-9LG specification tier. This wide range supports deployment in harsh environments such as automotive engine bays, industrial motor drives, and outdoor sensor enclosures. The device's thermal derating begins above 69°C, with power dissipation reduced by −5.5 mW/°C beyond that point to maintain reliability.
Does UPC277GR(20)-9LG-E2-A support true rail-to-rail output?
The UPC277GR(20)-9LG-E2-A provides rail-to-rail input (V− to V+ − 1.5 V) but not full rail-to-rail output: its output swings from V− (GND) up to V+ − 1.5 V under 2 kΩ load. This GND-referenced sink capability eliminates need for negative supplies in many single-supply designs, though high-side headroom remains limited. For applications requiring full V+ reach, external level-shifting or alternative op-amps must be considered.
Is UPC277GR(20)-9LG-E2-A pin-compatible with other μPC-series dual op-amps?
Yes - UPC277GR(20)-9LG-E2-A shares the same 8-pin TSSOP-9LG pinout and electrical behavior as μPC1251GR-9LG and μPC358GR-9LG, including identical pin assignments, absolute maximum ratings, and recommended operating conditions. This allows drop-in replacement within the same package variant, provided the DC parameter grade (e.g., "(20)" denotes standard grade, not DC-optimized "(5)") aligns with system accuracy requirements.
What is the significance of the "(20)" suffix in UPC277GR(20)-9LG-E2-A?
The "(20)" in UPC277GR(20)-9LG-E2-A indicates the DC parameter selection grade - specifically, the standard-grade version with ±2 mV typical input offset voltage and ±7 mV maximum. It distinguishes the part from the tighter-spec "(5)" variant (±2 mV typ, ±3 mV max). Both share identical pinout, package, and AC performance; the "(20)" grade is intended for general-purpose applications where moderate DC precision suffices.
Can UPC277GR(20)-9LG-E2-A be used in split-supply configurations?
Yes - UPC277GR(20)-9LG-E2-A supports split-supply operation from ±1.5 V to ±15 V, as confirmed in the Recommended Operating Conditions table. In this mode, V+ connects to +VS and V− connects to −VS, enabling traditional dual-rail analog signal processing. Its common-mode input range extends from −VS to (+VS − 1.5 V), preserving functionality across symmetric and asymmetric supply configurations without modification.
