8-channel 45V output, High Capacitive Drive Parametric Measurement Unit

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.
