DESCRIPTION
Easy-to-Use, Ultra-Tiny
16-Bit ΔΣ ADC
The LTC
2450 is an ultra-tiny 16-bit analog-to-digital
converter. The LTC2450 uses a single 2.7V to 5.5V supply,
accepts a single-ended analog input voltage, and commu-
nicates through an SPI interface. It includes an integrated
oscillator that does not require any external components.
It uses a delta-sigma modulator as a converter core and
provides single-cycle settling time for multiplexed applica-
tions. The converter is available in a 6-pin, 2mm × 2mm
DFN package. The internal oscillator does not require any
external components. The LTC2450 includes a proprietary
input sampling scheme that reduces the average input
sampling current several orders of magnitude.
The LTC2450 is capable of up to 30 conversions per sec-
ond and, due to the very large oversampling ratio, has
extremely relaxed antialiasing requirements. The LTC2450
includes continuous internal offset and full-scale calibra-
tion algorithms which are transparent to the user, ensuring
accuracy over time and over the operating temperature
range. The converter uses its power supply voltage as the
reference voltage and the single-ended, rail-to-rail input
voltage range extends from GND to VCC.
Following a conversion, the LTC2450 can automatically
enter a sleep mode and reduce its power to less than
200nA. If the user samples the ADC once a second, the
LTC2450 consumes an average of less than 50μW from
a 2.7V supply.
