5 / 12 page 5 LTC2401/LTC2402 VCC (Pin 1): Positive Supply Voltage. Bypass to GND (Pin 4) with a 10 µF tantalum capacitor in parallel with 0.1 µF ceramic capacitor as close to the part as possible. FSSET (Pin 2): Full-Scale Set Input. This pin defines the full-scale input value. When VIN = FSSET, the ADC outputs full scale (FFFFFH). The total reference voltage is FSSET – ZSSET. CH0, CH1 (Pins 4, 3): Analog Input Channels. The input voltage range is – 0.125 • VREF to 1.125 • VREF. For VREF > 2.5V, the input voltage range may be limited by the absolute maximum rating of – 0.3V to VCC + 0.3V. Conver- sions are performed alternately between CH0 and CH1 for the LTC2402. Pin 4 is a No Connect (NC) on the LTC2401. ZSSET (Pin 5): Zero-Scale Set Input. This pin defines the zero-scale input value. When VIN = ZSSET, the ADC outputs zero scale (00000H). GND (Pin 6): Ground. Shared pin for analog ground, digital ground, reference ground and signal ground. Should be connected directly to a ground plane through a mini- mum length trace or it should be the single-point-ground in a single-point grounding system. CS (Pin 7): Active LOW Digital Input. A LOW on this pin enables the SDO digital output and wakes up the ADC. Following each conversion, the ADC automatically enters the Sleep mode and remains in this low power state as long as CS is HIGH. A LOW on CS wakes up the ADC. A LOW-to-HIGH transition on this pin disables the SDO digital output. A LOW-to-HIGH transition on CS during the Data Output transfer aborts the data transfer and starts a new conversion. SDO (Pin 8): Three-State Digital Output. During the data output period, this pin is used for serial data output. When the chip select CS is HIGH (CS = VCC), the SDO pin is in a high impedance state. During the Conversion and Sleep periods, this pin can be used as a conversion status out- put. The conversion status can be observed by pulling CS LOW. SCK (Pin 9): Bidirectional Digital Clock Pin. In the Internal Serial Clock Operation mode, SCK is used as digital output for the internal serial interface clock during the data output period. In the External Serial Clock Operation mode, SCK is used as digital input for the external serial interface. An internal pull-up current source is automatically activated in Internal Serial Clock Operation mode. The Serial Clock mode is determined by the level applied to SCK at power up and the falling edge of CS. FO (Pin 10): Frequency Control Pin. Digital input that controls the ADC’s notch frequencies and conversion time. When the FO pin is connected to VCC (FO = VCC), the converter uses its internal oscillator and the digital filter’s first null is located at 50Hz. When the FO pin is connected to GND (FO = 0V), the converter uses its internal oscillator and the digital filter’s first null is located at 60Hz. When FO is driven by an external clock signal with a frequency fEOSC, the converter uses this signal as its clock and the digital filter first null is located at a frequency fEOSC/2560.
