www.ti.com SNIS150B – SEPTEMBER 2008 – REVISED JUNE 2013 1.5V, micro SMD, Dual-Gain Analog Temperature Sensor with Class AB Output
Check for Samples: LM94023 FEATURES DESCRIPTION The LM94023 is a precision analog output CMOS
integrated-circuit temperature sensor that operates at
a supply voltage as low as 1.5 Volts. Available in the
very small four-bump DSBGA 0.8mm x 0.8mm) the
LM94023 occupies very little board area. A class-AB
output structure gives the LM94023 strong output
source and sink current capability for driving heavy
loads, making it well suited to source the input of a
sample-and-hold analog-to-digital converter with its
transient load requirements, This generally means the
LM94023 can be used without external components,
like resistors and buffers, on the output. While
operating over the wide temperature range of -50В°C
to +150В°C, the LM94023 delivers an output voltage
that is inversely porportional to measured
temperature. The LM94023's low supply current
makes it ideal for battery-powered systems as well as
general temperature sensing applications. 1 2 Low 1.5V Operation
