Analog Devices Inc. EVAL-KW4503Z KWIK Demo Board

The EVAL-KW4503Z uses the ADA4510-2, a dual-channel, 40V, high-precision, low input bias current, low offset voltage, low offset voltage drift, low noise, rail-to-rail input, and output op-amp that can be used at any point of the signal chain, including sensing, conditioning, and output drive. With the use of Analog Devices, Inc.'s proprietary DigiTrim™ technique, the ADA4510-2 achieves best-in-class low offset drift (±70nV/°C typical, ±500nV/°C maximum) and low offset voltage (±5μV typical, ±20μV maximum), simplifying temperature calibrations in precision designs. The ADA4510-2 is specified from −40°C to +85°C and −40°C to +125°C and is available in an 8-lead, SOIC_N package.

The EVAL-KW4503Z uses one channel of the ADA4510-2 for the TIA stability KWIK demo, which provides a hands-on platform. The platform allows the user to select from three compensation options: a marginally stable design, a design with a 45° phase margin, and a design with >70° phase margin using the ADA4510 precision CMOS amplifier.

The Analog Devices EVAL-KW4503Z uses the other channel of the ADA4510-2 for the capacitive load stability KWIK demo, which provides a hands-on platform showing how to stabilize a precision, 10MHz op amp driving a 1nF capacitive load. The TIA and capacitive load demo are combined into a single, easy-to-use board that plugs directly into the ADALM2000. A typical application for this demo board is advanced education.
