ADA4510-2

• Enables stability analysis of ADA4510-2 configured as a Transimpedance Amplifier (TIA) and a unity gain follower driving a capacitive load.
• Easy connection to ADALM2000

The EVAL-KW4503Z is a know-how with integrated knowledge (KWIK) demonstration board designed to familiarize its users how to predict, measure, and simulate the stability and phase margin of an operational amplifier (op amp). It enables the stability analysis of the ADA4510-2 configured as a transimpedance amplifier (TIA) and a unity gain follower driving a capacitive load.

The EVAL-KW4503Z uses the ADA4510-2, which is a dual-channel, 40 V, high-precision, low input bias current, low offset voltage, low offset voltage drift, low noise, rail-to-rail input, and output operational amplifier 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 (±70 nV/°C typical, ±500 nV/°C maximum) and low offset voltage (±5 μV typical, ±20 μV 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.

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

The 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, 10 MHz op amp driving a 1nF capacitive load.

Both the TIA demo and capacitive load demo are combined into a single, easy-to-use board that plugs directly into the ADALM2000.
