= -40 to +85 °C; V1+ = V2+ = +2.5 V, ±5%; V1- =
V2- = -2.5 V, ±5%; VL -VLR = 3.3 V, ±5%; VREF = (VREF+) - (VREF-) = 4.096V; MCLK = 8 MHz; SMODE = VL.;
BUFEN = V1+ unless otherwise stated. Connected per
.
5.
For optimum performance, VREF+ should always be less than (V+) - 0.2 volts to prevent saturation of the VREF+ input buffer.
6.
Specification is for MCLK = 8MHz and 5 kSps conversion rate. MCLK frequency and conversion rate affect power consumption.
See
Section 3.2 Power Consumption
for more details.
7.
Tested with 100 mVP-P on any supply up to 2 kHz. V1+ and V2+ supplies at the same voltage potential, V1- and V2- supplies at
the same voltage potential.
