The converter is based on a +125°C Ambient Operating Temperature successive-approximation register architecture with Range an internal track-and-hold circuit. It can be configured to accept up to eight input signals at inputs IN0 • Eight Input Channels through IN7. • Variable Power Management The output serial data is straight binary and is • Independent Analog and Digital Supplies compatible with several standards, such as SPI, • Compatible With SPI™, QSPI™, MICROWIRE, QSPI, MICROWIRE, and many common DSP serial and DSP interfaces. • Packaged in 16-Pin TSSOP The ADC128S052x may be operated with • Conversion Rate 200 kSPS to 500 kSPS independent analog and digital supplies. The analog supply (VA) can range from 2.7 V to 5.25 V, and the • DNL (VA = VD = 5 V) + 1.3 or −0.9 LSB digital supply (VD) can range from 2.7 V to VA. (Maximum) Normal power consumption using a 3-V or • INL (VA = VD = 5 V) ±1 LSB (Maximum) 5-V supply is 1.6 mW and 8.7 mW, respectively. The • Power Consumption power-down feature reduces the power consumption – 3-V Supply 1.6 mW (Typical) to 0.06 µW using a 3-V supply and 0.25 µW using a 5-V supply. – 5-V Supply 8.7 mW (Typical) The ADC128S052x is packaged in a 16-pin TSSOP 2 Applications package. The ADC128S052 is ensured over the extended industrial temperature range of −40°C to • Automotive Navigation +105°C while the ADC128S052-Q1 is ensured to an • Portable Systems AECQ100 Grade-1 automotive temperature range of • Medical Instruments −40°C to +125°C. • Mobile Communications Device Information(1) • Instrumentation and Control Systems PART NUMBER PACKAGE BODY SIZE (NOM) ADC128S052, TSSOP (16) 4.40 mm × 5.00 mm ADC128S052-Q1 (1) For all available packages, see the orderable addendum at the end of the data sheet.
