UPC4570GR-9LG-E2-A

Instrumentation, Op Amps, Buffer Amps Overview

The UPC4570GR-9LG-E2-A is a dual operational amplifier from the Renesas Electronics UPC4570 series, housed in an 8-pin plastic TSSOP package. It features a gain-bandwidth product of 15 MHz and a slew rate of 7 V/µs. The device operates within a supply voltage range of 4 V to 16 V, with a typical operating supply current of 5 mA. Key electrical characteristics include an input offset voltage of ±300 µV, an input bias current of 400 nA, and a common-mode rejection ratio of 100 dB. The input voltage noise density is specified at 4.5 nV/√Hz, while the input current noise density is 700 fA/√Hz. It supports an output current of 10 mA per channel and functions reliably across an ambient temperature range of -40 °C to +85 °C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix E2 indicates the take-up side pin 1 orientation for the embossed tape packaging format. Confirm the GR-9LG designation corresponds to the 8-pin plastic TSSOP outline. Ensure the component meets the required -40 °C to +85 °C operating temperature range for your application environment. Cross-reference the datasheet revision to confirm parameter consistency before finalizing procurement specifications.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when superior noise performance and higher bandwidth are required compared to standard general-purpose amplifiers like the 4558. The UPC4570 offers significantly improved gain-bandwidth product and slew rate while maintaining stability in voltage follower configurations. Consider the TSSOP package for space-constrained designs requiring surface-mount technology. Verify that the 10 mA output current capability meets the load requirements of the target circuit.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the UPC4570 family, which serves as a high-performance upgrade to the legacy UPC258 and 4558 operational amplifiers. The series is designed to provide enhanced AC performance, including lower input equivalent noise voltage and faster transient response. The UPC4570GR variant specifically extends the operating temperature range to support industrial applications, distinguishing it from commercial grade counterparts.
