TMS320F28374D

Specifications

(1)

Typical values are measured with VREFHI = 2.5 V and VREFLO = 0 V. Minimum and Maximum values are tested or characterized with

VREFHI = 2.5 V and VREFLO = 0 V.

(2)

See Section 5.10.1.2.2.

(3)

No missing codes.

(4)

AC parameters will be impacted by clock source accuracy and jitter, this should be taken into account when selecting the clock source

for the system. The clock source used for these parameters was a high-accuracy external clock fed through the PLL. The on-chip

Internal Oscillator has higher jitter than an external crystal and these parameters will degrade if it is used as a clock source.

(5)

I/O activity is minimized on pins adjacent to ADC input and VREFHI pins as part of best practices to reduce capacitive coupling and

crosstalk.

(6)

One ADC operating while all other ADCs are idle.

(7)

All ADCs operating with identical ADCCLK, S+H durations, triggers, and resolution.

(8)

Any ADCs operating with heterogeneous ADCCLK, S+H durations, triggers, or resolution.

(9)

Maximum DC code deviation due to operation of multiple ADCs simultaneously.

(10) Value based on characterization.
