LTC2450

Easy-to-Use, Ultra-Tiny

16-Bit DS ADC

Features

Description

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

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

includes continuous internal offset and full-scale calibra-

accuracy over time and over the operating temperature

range. The converter uses its power supply voltage as the

Instrumentation

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.
