TS7001 A Micropower, 2-channel, 187.5-ksps, Serial-Output 12-bit SAR ADC FEATURES DESCRIPTION Pin-for-pin, 1.5x Faster Upgrade to AD7887 The TS7001 a pin-for-pin, 1.5x faster alternate to Single-supply Operation: +2.7V to +3.6V the AD7887 - is a self-contained, 2-channel, high- INL: 1LSB speed, micropower, 12-bit analog-to-digital converter One or Two Single-ended Analog Inputs (ADC) that operates from a single +2.7V to +3.6V Internal Wide-bandwidth Track-and-Hold power supply. The TS7001 is capable of a 187.5-ksps Integrated +2.5-V Reference throughput rate with an external 3 MHz serial clock Flexible Power/Throughput-Rate Management and draws 0.85mA supply current. 0.85mA at 187.5ksps (Internal VREF ON) The wideband input track-and-hold acquires signals 0.7mA at 187.5ksps (Internal VREF OFF) in 500ns and features a single-ended sampling Shutdown-mode Supply Current: 1 A (max) topology. Output data coding is straight binary and SPI/QSPI/MICROWIRE/DSP-Compatible the ADC is capable of converting full power signals 1 Serial Interfaces up to 10 MHz. The ADC also contains an integrated Operating Temperature Range: -40C to +85C 2.5V reference or the VREF pin can be overdriven by 8-pin MSOP Packaging an external reference. The TS7001s provides one or two analog inputs APPLICATIONS . In each with an analog input range from 0 to VREF Instrumentation and Control Systems two-channel operation, the analog input range is 0V High-Speed Modems to VDD. Efficient circuit design ensures low power Battery-powered systems: consumption of 2mW (typical) for normal operation Personal Digital Assistants, Medical and 3 W in power-down operation. Instruments, Mobile Communications The TS7001 is fully specified from -40C to +85C and is available in 8-pin MSOP package. FUNCTIONAL BLOCK DIAGRAM 1 SPI and QSPI are trademarks of Motorola, Inc.
