6 / 20 page LTC2460/LTC2462 6 24602f PIN FUNCTIONS REFOUT (Pin 1): Reference Output Pin. Nominally 1.25V, this voltage sets the fullscale input range of the ADC. For noise and reference stability connect to a 0.1μF capacitor tied to GND. This capacitor value must be less than or equal to the capacitor tied to the reference compensation pin (COMP). REFOUT cannot be overdriven by an external reference. For applications that require an input range greater than 0V to 1.25V, please refer to the LTC2450/ LTC2452. COMP (Pin 2): Internal Reference Compensation Pin. For low noise and reference stability, tie a 0.1μF capacitor to GND. CS (Pin 3): Chip Select (Active LOW) Digital Input. A LOW on this pin enables the SDO output. A HIGH on this pin places the SDO output pin in a high impedance state and any inputs on SDI and SCK will be ignored. SDI (Pin 4): Serial Data Input Pin. This pin is used to program the sleep mode and 30Hz/60Hz output rate (LTC2460). SCK (Pin 5): Serial Clock Input. SCK synchronizes the serial data input/output. Once the conversion is complete, a new data bit is produced at the SDO pin following each SCK falling edge. Data is shifted into the SDI pin on each rising edge of SCK. SDO (Pin 6): Three-State Serial Data Output. SDO is used for serial data output during the DATA INPUT/OUTPUT state and can be used to monitor the conversion status. GND (Pins 7, 11): Ground. Connect directly to the ground plane through a low impedance connection. REF– (Pin 8): Negative Reference Input to the ADC. The voltage on this pin sets the zero input to the ADC. This pin should tie directly to ground or the ground sense of the input sensor. IN+ (LTC2462), IN (LTC2460) (Pin 9): Positive input volt- age for the LTC2462 differential device. ADC input for the LTC2460 single-ended device. IN– (LTC2462), GND (LTC2460) (Pin 10): Negative input voltage for the LTC2462 differential device. GND for the LTC2460 single-ended device. VCC (Pin 12): Positive Supply Voltage. Bypass to GND with a 10μF capacitor in parallel with a low-series-induc- tance 0.1μF capacitor located as close to the device as possible. Exposed Pad (Pin 13 – DFN Package): Ground. Connect directly to the ground plane through a low impedance connection.
