out-of-band noise; while providing a reduced sample rate output to minimize the amount

DSP processing bandwidth required to fully process the digitized waveform.

The eQADC provides the following features:

●

Dual on-chip ADCs

–2

× 12-bit ADC resolution

–

Programmable resolution for increased conversion speed (12-bit, 10-bit, 8-bit)

12-bit conversion time – 938 ns (1 M sample/s)

10-bit conversion time – 813 ns (1.2 M sample/s)

8-bit conversion time – 688 ns (1.4M sample/s)

–

Up to 10-bit accuracy at 500K sample/s and 8-bit accuracy at 1M sample/s

–

Differential conversions

–

Single-ended signal range from 0 to 5 V

–

Sample times of 2 (default), 8, 64, or 128 ADC clock cycles

–

Provides time stamp information when requested

–

Allows time stamp information relative to eTPU clock sources, such as an angle

clock

–

Parallel interface to eQADC command FIFOs (CFIFOs) and result FIFOs

(RFIFOs)

–

Supports both right-justified unsigned and signed formats for conversion results

●

40 single-ended input channels, expandable to 56 channels with external multiplexers

(supports 4 external 8-to-1 muxes)

●

8 channels can be used as 4 pairs of differential analog input channels

●

Differential channels include variable gain amplifier for improved dynamic range (

×1,

×2, ×4)

●

Differential channels include programmable pull-up and pull-down resistors for biasing

and sensor diagnostics (200 k

Ω, 100 kΩ, 5kΩ)

●

Additional internal channels for monitoring voltages (such as core voltage, I/O voltage,

LVI voltages, etc.) inside the device

●

An internal bandgap reference to allow absolute voltage measurements

●

Silicon die temperature sensor

–

Provides temperature of silicon as an analog value

–

Read using an internal ADC analog channel

–

May be read with either ADC

●

2 decimation filters

–

Programmable decimation factor (1 to 16)

–

Selectable IIR or FIR filter

–

Up to 4th order IIR or 8th order FIR

–

Programmable coefficients

–

Saturated or non-saturated modes

–

Programmable Rounding (Convergent; Two’s Complement; Truncated)
