[a] No measurement in mass production; parameter is guaranteed by design and/or quality observation.

[b] The specified resistor values are valid for connection loss at the bridge sensor input BR1P and BR1N pins.

 For detection of a connection loss at the positive bridge supply TOP pin, the voltage level at BR1P and/or BR1N must fall below 11% of the

voltage level between the VDDA and VSSA pins.

 For detection of a connection loss at the negative bridge supply BOT pin, the voltage level at BR1P and/or BR1N must rise above 66% of the

voltage level between the VDDA and VSSA pins.

[c] No bridge settling included in timing.

[d] Dependent on the configuration. The specified limit is valid only for ADC resolutions

 15 bits.

[e] FSO: full-scale output. No sensor-caused effects are included in the overall error. ADC input range from 10% to 90% of VSENS; DAC from 5% to

95% of output range.

[f] Power ON/OFF thresholds are tested for functionality in mass production; no level test is processed.

[g] Minimum is | I_OUT | ≥ 6mA driving current.

[h] Maximum limit is | I_OUT_MAX | ≤ 25mA
