The TSMU818A045 is a high-performance, highly integrated parametric measurement unit (PMU) consisting of eight independent channels. Each channel includes one voltage output DAC that sets the programmable input levels for the force voltage amplifier, and two clamp input DACs. Five resistor-based, programmable, force-and-measure current ranges are available, ranging from ±5µA to ±100mA. Four of these ranges use on-chip sense resistors.

Measurements for the eight channels can be multiplexed in a wired-or configuration, which eliminates the need for an external multiplexer. Individual measurement outputs for respective channels are also available. The PMU functions are controlled using a simple SPI-compatible serial interface. An interface clock of 80MHz allows for fast-mode updates and state changes with the dual-state, double-buffered architecture. Configuration registers provide the ability to easily change force or measure conditions, DAC levels, and selected current ranges.
