Features
— 4 × 12-bit ADC resolution
— Programmable resolution for increased conversion speed (12-bit, 10-bit, 8-bit)
– 12-bit conversion time as low as1 µS (as fast as 1 M sample/sec)
– 10-bit conversion time as low as 867 nS (as fast as 1.2 M sample/sec)
– 8-bit conversion time as low as 733 nS (as fast as 1.4 M sample/sec)
— Accuracy as high as 10-bit accuracy at 500 K sample/sec and 8-bit accuracy at 1 M sample/sec
— Differential conversions
— Single-ended signal range from 0 to 5 V
— Variable gain amplifiers on differential inputs (×1, ×2, ×4)
— Sample times of 2 (default), 8, 64, or 128 ADC clock cycles
— Provides time stamp information when requested
— Supports both right-justified unsigned and signed formats for conversion results
• 64 input channels, including 16 channels which can each be converted simultaneously by each
eQADC
• Eight additional internal channels for measuring control and monitoring voltages inside the device
— Including core voltage, I/O voltage, and low-voltage interrupt (LVI) voltages
• As many as eight inputs can be configured as four pairs of differential analog input channels
— Programmable pull-up/pull-down resistors on each differential input
• Silicon die temperature sensor
— Provides temperature of silicon as an analog value
— Read using an internal ADC analog channel
• Four decimation filters
— Programmable decimation factor (2 to 16)
— Selectable IIR or FIR filter
— Fully programmable 4th order IIR or 8th order FIR
— Saturated or non-saturated modes
— Programmable rounding (convergent; two’s complement; truncated)
— Pre-fill mode to pre-condition the filter before the sample window opens
• Full duplex synchronous serial interface to an external device
— Free-running clock for use by an external device
— Supports a 26-bit message length
• Six priority-based queues per ADC
• Trigger sources include software, timer channels and input pins
• eTPU result interface
— Allows any ADC result to be exported to eTPU for use with reaction channels
• Support for an additional 64 – 8 = 56 channels via external multiplexing
