Excalibur™ LOW-NOISE HIGH-SPEED

PRECISION OPERATIONAL AMPLIFIER

SLOS511 – JUNE 2007

APPLICATION INFORMATION (continued)

Macromodel information provided was derived using Microsim Parts™, the model generation software used with

Microsim PSpice™. The Boyle macromodel (see Note and Figure 47) and subcircuit (see Figure 48) were

generated using the TLE202x7 typical electrical and operating characteristics at 25

°C. Using this information,

output simulations of the following key parameters can be generated to a tolerance of 20% (in most cases):

• Maximum positive output voltage swing

• Gain-bandwidth product

• Maximum negative output voltage swing

• Common-mode rejection ratio

• Slew rate

• Phase margin

• Quiescent power dissipation

• DC output resistance

• Input bias current

• AC output resistance

• Open-loop voltage amplification

• Short-circuit output current limit

Integrated Circuit Operational Amplifiers", IEEE Journal of Solid-State Circuits, SC-9,
