1 Description
The THS4521, THS4522, and THS4524 family of devices are very low-power, fully differential operational
amplifiers with rail-to-rail output and an input common-mode range that includes the negative rail. These
amplifiers are designed for low-power data-acquisition systems and high-density applications where power
dissipation is a critical parameter.
The THS4521EVM is an evaluation module (EVM) for the single version, THS4521, in an SO-8 (D)
package. The THS4522EVM is an evaluation module for the dual version, THS4522, in a TSSOP-16 (PW)
package. The THS4524EVM is an evaluation module for the quad version, THS4524, in a TSSOP-32
(DBT) package.
The THS4521/2/4EVMs are designed to quickly and easily demonstrate the functionality and versatility of
these amplifiers. Each EVM is ready to connect to power, a signal source, and a variety of test
instruments through the use of onboard connectors. The default amplifier configuration for each module is
a single-ended input, single-ended output (via transformer), and split-supply operation. The EVMs can be
easily configured for differential input, differential output, and single-supply operation. Throughout this
document, the acronym EVM and the phrases evaluation module and evaluation board are synonymous
with the THS4521/2/4EVMs. For clarity of reading, the abbreviation THS4521/2/4EVMs refers to the
THS4521EVM, THS4522EVM, and THS4524EVM, unless otherwise noted.
The electrical specifications for the THS4521/2/4EVMs are summarized in Table 1.
