MAX11156
18-Bit, 500ksps, ±5V SAR ADC
with Internal Reference in TDFN
Electrical Characteristics (continued)
(V_DD = 4.75V to 5.25V, V_OVDD = 2.3V to 5.25V, f_SAMPLE = 500kHz, V_REF = 4.096V, Reference Mode 3; T_A = T_MIN to T_MAX, unless
otherwise noted. Typical values are at T_A = +25NC.) (Note 2)
Note 2: Maximum and minimum limits are fully production tested over specified supply voltage range and at a temperature of +25°C
and +85°C. Limits below +25°C are guaranteed by design and device characterization. Typical values are not guaranteed.
Note 3: See the Analog Inputs and Overvoltage Input Clamps sections.
Note 4: See the Definitions section.
Note 5: Defined as the change in positive full-scale code transition caused by a Q5% variation in the V_DD supply voltage.
Note 6: 10kHz sine wave input, -0.1dB below full scale.
Note 7: See Table 4 for definition of the reference modes.
Note 8: f_IN1 = 9.4kHz, f_IN2 = 10.7kHz, Each tone at -6.1dB below full scale.
Note 9: C_LOAD = 65pF on DOUT.
Typical Operating Characteristics
(V_DD = 5V, V_OVDD = 3.3V, f_SAMPLE = 500kHz, V_REF = 4.096V, Reference Mode 3, T_A = +25NC, unless otherwise noted.)
