3 Description

The TSMU818A030 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. Interface clock of 80MHz allows for fast

mode updates and state changes with the dual-state

double-buffered architecture. Configuration registers

allow the user to easily change force or measure

conditions, DAC levels, and selected current ranges.
