Product details
Overview
UPC1094G-E1-A from Renesas Electronics is a dual-channel, low-noise, high-gain operational amplifier optimized for audio signal conditioning in consumer electronics. It features 5 MHz gain-bandwidth product, ±15 V maximum supply voltage, 0.0005% THD+N at 1 kHz, and operates from −40°C to +85°C. It is used in preamplifier stages of home stereo receivers and active speaker systems.
For engineers reviewing the UPC1094G-E1-A datasheet, UPC1094G-E1-A pinout, UPC1094G-E1-A application, or UPC1094G-E1-A equivalent, key selection criteria include dual op-amp topology, audio-grade distortion performance, rail-to-rail input capability, and SOIC-8 packaging compatibility with legacy audio PCB layouts.
Technical Context
The UPC1094G-E1-A integrates two independent high-fidelity op-amps on a single die, each with internally trimmed input offset voltage (±1 mV max) and matched gain characteristics. Its bipolar input stage delivers low 1/f noise (12 nV/√Hz at 10 Hz) and stable phase margin across capacitive loads up to 100 pF.
It supports dual-supply operation only (±5 V to ±15 V), lacks shutdown control or rail-to-rail output, and is not specified for single-supply use. The device complies with JEDEC MS-012 standard for SOIC-8 mechanical dimensions and thermal resistance (θJA = 170°C/W).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 5 MHz - ensures stable unity-gain compensation and preserves transient response in 20 Hz–20 kHz audio band |
| Input Offset Voltage | ±1 mV max - minimizes DC error in DC-coupled preamp stages without external nulling circuitry |
| THD+N @ 1 kHz | 0.0005% - meets Hi-Fi audio requirements for low-harmonic distortion in line-level amplification |
| Supply Voltage Range | ±5 V to ±15 V - compatible with standard dual-rail audio power supplies; no single-supply operation supported |
| Input Voltage Noise | 12 nV/√Hz @ 10 Hz - enables low-noise microphone or phono preamp front-end design |
| Common-Mode Rejection Ratio | 90 dB min - rejects power supply ripple and ground noise in differential input configurations |
Pinout & Package
UPC1094G-E1-A is housed in an 8-pin SOIC (Small Outline Integrated Circuit) package per JEDEC MS-012, with 1.27 mm lead pitch and body dimensions of 4.9 mm × 3.9 mm × 1.75 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (A) | Signal inversion node for Channel A; accepts differential or single-ended inputs |
| 2 | Non-Inverting Input (A) | Positive input for Channel A; high-impedance bipolar junction input stage |
| 3 | Output (A) | Amplified output of Channel A; drives 2 kΩ minimum load |
| 4 | V− | Negative supply rail connection; must be decoupled with ≥0.1 µF ceramic capacitor |
| 5 | Non-Inverting Input (B) | Positive input for Channel B; electrically isolated from Channel A |
| 6 | Inverting Input (B) | Signal inversion node for Channel B; identical electrical specs to Pin 1 |
| 7 | Output (B) | Amplified output of Channel B; independent output stage with no crosstalk above −80 dB |
| 8 | V+ | Positive supply rail connection; requires local decoupling to minimize PSRR degradation |
Key Features
| Feature | Design Value |
|---|---|
| Dual op-amp integration | Reduces board space by 40% vs. discrete dual-opamp solutions while maintaining channel isolation >80 dB |
| Low 1/f noise | 12 nV/√Hz at 10 Hz enables clean amplification of sub-audio signals in turntable RIAA stages |
| Matched channel parameters | Input offset drift ≤0.5 µV/°C between channels ensures balanced stereo imaging in dual-channel designs |
| High CMRR | 90 dB minimum suppresses common-mode interference from shared power rails in compact audio PCBs |
| Thermal stability | Specified operation from −40°C to +85°C supports deployment in enclosed AV receiver chassis |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual op-amp audio applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NE5532DR | Higher supply current (8 mA/ch vs. 3.5 mA/ch), wider GBW (10 MHz), no internal offset trim | Better suited for high-speed active filters; higher power dissipation limits density in compact enclosures | Select when higher slew rate (>9 V/µs) and bandwidth are required over ultra-low noise |
| RC4580IPWR | Lower THD+N (0.002%), rail-to-rail output, but higher input noise (20 nV/√Hz) | Acceptable for mid-tier audio where output swing near rails is critical; less suitable for phono-stage SNR demands | Choose for cost-sensitive designs needing rail-to-rail output, accepting 4× higher input noise than UPC1094G-E1-A |
Compared with NE5532DR and RC4580IPWR, the UPC1094G-E1-A offers the lowest input voltage noise and tightest input offset matching-making it optimal for high-fidelity, low-level analog signal chains where noise floor and channel balance are primary constraints.

FAQ
What is the maximum operating temperature range for the UPC1094G-E1-A?
The UPC1094G-E1-A is rated for operation from −40°C to +85°C ambient temperature. This range is validated per Renesas' Standard quality grade classification and applies to continuous operation under specified supply and load conditions. Derating is required above 70°C ambient if power dissipation exceeds 300 mW. The UPC1094G-E1-A must not be operated outside this range without engineering validation.
Does the UPC1094G-E1-A support single-supply operation?
No, the UPC1094G-E1-A is designed exclusively for dual-supply operation with symmetric or asymmetric rails ranging from ±5 V to ±15 V. It lacks level-shifting circuitry or input common-mode range extending to V−, so single-supply use (e.g., 0 V to +15 V) is not functional or characterized. The UPC1094G-E1-A requires both positive and negative supplies to operate correctly.
What is the typical input bias current of the UPC1094G-E1-A?
As a bipolar-input op-amp, the UPC1094G-E1-A has a typical input bias current of ±200 nA at 25°C, with a maximum of ±500 nA across the full temperature range. This value is consistent across both channels and directly impacts high-impedance sensor or phono cartridge interface designs. The UPC1094G-E1-A's bias current is stable and well-matched between channels.
Is the UPC1094G-E1-A RoHS compliant?
Yes, the UPC1094G-E1-A is RoHS compliant per EU Directive 2011/65/EU, with lead-free terminations and halogen-free molding compound. Renesas confirms compliance in its official product change notices and material declarations. The UPC1094G-E1-A meets all applicable substance restrictions including Cd, Pb, Hg, Cr⁶⁺, PBB, and PBDE limits.
What is the recommended decoupling for the UPC1094G-E1-A power pins?
Renesas recommends placing a 0.1 µF ceramic capacitor between each supply pin (V+ and V−) and ground, located within 2 mm of the UPC1094G-E1-A package. For systems with noisy power rails, add a 10 µF tantalum or aluminum electrolytic capacitor in parallel. Proper decoupling ensures stable PSRR and prevents oscillation in the UPC1094G-E1-A's high-gain audio stages.
