Checkfor Samples: ADC108S022
1FEATURES DESCRIPTIONThe ADC108S022 isa low-power, eight-channel
Eight Input Channels CMOS 10-bit analog-to-digital converter specified for
• Variable Power Management conversion throughput ratesof 50 kspsto 200 ksps.
Independent Analog and Digital Supplies The converter is based on a successive-
approximation register architecture with an internal
• SPI/QSPI/MICROWIRE/DSP compatible track-and-hold circuit.It can be configuredto accept
• Packagedin 16-Lead TSSOP upto eight input signalsat inputs IN0 through IN7.
The output serial data is straight binary and is
APPLICATIONS compatible with several standards, such as SPI,
• Automotive Navigation QSPI, MICROWIRE, and many common DSP serial
Portable Systems interfaces.
Medical Instruments The ADC108S022 maybe operated with independent
Mobile Communications analog and digital supplies. The analog supply (VA)
can range from +2.7V to +5.25V, and the digital
• Instrumentation and Control Systems supply (VD) can range from +2.7Vto VA. Normal
power consumption usinga +3Vor +5V supplyis 1.1
KEY SPECIFICATIONS mW and 6.4 mW, respectively. The power-down
Conversion Rate50 kspsto 200 ksps feature reduces the power consumptionto 0.09µ W
usinga +3V supply and 0.3µ W usinga +5V supply.
• DNL (VA= VD= 2.7Vto 5.25V) ±0.3 LSB (max)The ADC108S022is packagedina 16-lead TSSOP
• INL (VA= VD= 2.7Vto 5.25V) ±0.3 LSB (max)package. Operation over the extended industrial
• Power Consumption temperature rangeof −40°Cto +105°Cis ensured.
