Renesas UPC277GR(21)-9LG-E1-A

Overview

UPC277GR(21)-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 1.2 mA maximum supply current at +5 V. It serves as a general-purpose signal conditioning IC in sensor interface and portable analog front-ends.

For engineers reviewing the UPC277GR(21)-9LG-E1-A datasheet, UPC277GR(21)-9LG-E1-A pinout, UPC277GR(21)-9LG-E1-A application, or UPC277GR(21)-9LG-E1-A equivalent, key selection considerations include its TSSOP-8 (5.72 mm) package, −40°C to +125°C operating temperature range, low-voltage single-supply capability (+3 V to +30 V), and guaranteed output sink/source drive (10–40 mA).

Technical Context

This dual op-amp employs a bipolar PNP-input stage enabling true single-supply operation with common-mode input range extending to V− (GND), and a Class C push-pull output stage delivering rail-to-rail sinking and sourcing capability. Its internal frequency compensation ensures unity-gain stability without external components.

The device supports both single-ended (V− = GND, V+ = +3 to +30 V) and split-supply (±1.5 to ±15 V) configurations. Channel separation exceeds 120 dB at 1–20 kHz, and it includes output short-circuit protection with indefinite safe duration under specified thermal conditions.

FAQ

What is the maximum supply voltage for UPC277GR(21)-9LG-E1-A?

The absolute maximum supply voltage between V+ and V− is +32 V. For reliable operation, the recommended single-supply range is +3 V to +30 V. Exceeding +30 V risks parametric degradation or permanent damage, especially at elevated temperatures. Always observe derating curves-power dissipation must be reduced by −5.5 mW/°C above TA = 69°C per the datasheet's thermal specifications for the TSSOP-8 (5.72 mm) package. UPC277GR(21)-9LG-E1-A must never be operated beyond these limits to maintain long-term reliability.

Does UPC277GR(21)-9LG-E1-A support rail-to-rail output?

UPC277GR(21)-9LG-E1-A provides rail-to-rail *input* (common-mode range from V− to V+ − 1.5 V) but not full rail-to-rail output: its output swings from 0 V (GND) up to V+ − 1.5 V under 2 kΩ load. This GND-referenced output is ideal for single-supply ADC drivers and sensor interfaces, though it cannot reach the positive rail. The Class C push-pull output stage ensures low crossover distortion and 10–40 mA drive capability. UPC277GR(21)-9LG-E1-A does not require external pull-up resistors to achieve GND-level output.

What is the operating temperature range of UPC277GR(21)-9LG-E1-A?

UPC277GR(21)-9LG-E1-A is rated for −40°C to +125°C operating ambient temperature, qualifying it for under-hood automotive, industrial motor control, and outdoor equipment applications. This extended grade exceeds the −40°C to +85°C range of standard equivalents like LM358. Thermal derating begins at TA = 69°C (−5.5 mW/°C), and junction temperature must remain below 150°C. UPC277GR(21)-9LG-E1-A's qualification aligns with Renesas' "Standard" quality grade for industrial robots and transportation systems.

Can UPC277GR(21)-9LG-E1-A be used with split supplies?

Yes, UPC277GR(21)-9LG-E1-A supports split-supply operation with ±1.5 V to ±15 V. Its bipolar PNP input stage and symmetric design allow full functionality in dual-rail configurations-e.g., ±5 V or ±12 V-while retaining the same input offset, gain, and output drive specs. In split mode, the common-mode input range centers around 0 V, and output swing extends ±(V+ − 1.5 V). UPC277GR(21)-9LG-E1-A maintains identical performance whether configured for single or split supply, simplifying design reuse across platforms.

Is UPC277GR(21)-9LG-E1-A RoHS-compliant and lead-free?

Yes, UPC277GR(21)-9LG-E1-A is Pb-free: it contains no lead in external electrodes or other parts, complying with EU RoHS Directive requirements. The "E1-A" suffix denotes lead-free, tape-and-reel packaging (12 mm embossed taping, pin 1 on draw-out side). Renesas confirms this part meets JEDEC J-STD-020 moisture sensitivity level (MSL) 3 and requires standard reflow profiles (peak 260°C, ≤60 s at ≥220°C). UPC277GR(21)-9LG-E1-A is fully compatible with modern lead-free assembly processes.
