Notes:
1 See Terminology
2 Temperature ranges are as follows: B Version: -40°C to +125°C.
3 DC specifications tested with the outputs unloaded.
4 Linearity is tested using a reduced code range:; ADT7316 (code 115 to 4095); ADT7317 (code 28 to 1023); ADT7318 (code 8 to 255)
5 Guaranteed by Design and Characterization, not production tested
6 In order for the amplifier output to reach its minimum voltage, Offset Error must be negative. In order for the amplifier output to reach its maximum voltage, V
REF=VDD
and "Offset plus Gain" Error must be positive.
7 The SDA & SCL timing is measured with the input filters turned on so as to meet the Fast-Mode I2C specification. Switching off the input filters improves the transfer
rate but has a negative affect on the EMC behaviour of the part.
8 Guaranteed by design. Not tested in production.
9 Guaranteed by design and characterization, not production tested.
10 All input signals are specified with tr = tf = 5 ns (10% to 90% of V
DD) and timed from a voltage level of 1.6 V.
11 Measured with the load circuit of Figure 3.
12 I
DD spec. is valid for all DAC codes. Interface inactive. All DACs active. Load currents excluded.
Specifications subject to change without notice.
