Tools & Simulations

LTspice 1

Models for the following parts are available in LTspice:

  • LTC6226

Signal Chain Designer - BETA

Signal Chain Designer is a web-based tool designed to create and simulate complex precision signal chains. See your circuit’s performance before you commit to your PCB: transfer function, noise, power consumption, input range, and DC error. Quickly experiment with different parts and architectures. Signal chains can be exported to LTspice for further analysis.

Open Tool

Analog Filter Wizard

Use the Analog Filter Wizard to design low-pass, high-pass, or band-pass filters with actual op amps in minutes. As you progress through the design process, you can observe the characteristics of your filter design from ideal specifications to real world circuit behavior. Quickly evaluate the tradeoffs in op amp specifications - including gain-bandwidth, noise, and supply current – to determine the best filter design for your requirements.

Open Tool

Analog Photodiode Wizard

Use Photodiode Wizard to design a transimpedance amplifier circuit to interface with a photodiode. Select a photodiode from the library included in the tool, or enter custom photodiode specifications. Quickly observe tradeoffs between Bandwidth, Peaking (Q), and ENOB/SNR. Modify circuit parameters, and immediately see results in plots for pulse response, frequency response, and noise gain.

Product Details

The EVAL-LTC6226S8/EVAL-LTC6228IS8 allow the evaluation of the LTC6226 and the LTC6228, 8-lead, single channel, small outline integrated circuit (SOIC_N), 150 mil op amps. The EVAL-LTC6226S8 and EVAL-LTC6228IS8 are prepopulated boards on a buffer configuration with a post low-pass filter. This configuration allows the LTC6226 and the LTC6228 to be used as a high speed analog-to-digital converter (ADC) drivers. The EVAL-LTC6226S8/EVAL-LTC6228IS8 support other typical configurations of an op amp and have provisions for typical applications of the LTC6226 and the LTC6228, which include an active filter. The SHDN_N pin can be shunt to the VCC pin or the VEE pin, or to an external voltage drive.

The 4-layer EVAL-LTC6226S8/EVAL-LTC6228IS8 accept edge mounted, Subminiature Version A (SMA) connectors on both inputs and outputs to provide an efficient connection to the test equipment and other circuitry. In addition, the EVAL-LTC6226S8/EVAL-LTC6228IS8 have sufficient test points for signal pins and groundings.

Optimized power and ground planes ensure low noise and high speed operation. Component placement and power supply bypassing are optimized for maximum circuit flexibility and performance. The EVAL-LTC6226S8/EVAL-LTC6228IS8 accept C0402 or C0603 surface-mount technology (SMT) components and C1206 bypass capacitors for C8 and C9.

All components are placed on the primary side of the EVAL-LTC6226S8/EVAL-LTC6228IS8, and no components are placed on the secondary side. The EVAL-LTC6226S8 and EVAL-LTC6228IS8 evaluation boards are identical except for the on-board devices.

For full details on the LTC6226 and the LTC6228, see the LTC6226 and the LTC6228 data sheets, which must be consulted in conjunction with the user guide when using the EVAL-LTC6226S8/EVAL-LTC6228IS8.
