MAX11270 Datasheet, PDF (8/46 Pages) Maxim Integrated Products – Integrated PGA

MAX11270
24-Bit, 10mW, 130dB SNR, 64ksps Delta-Sigma
ADC with Integrated PGA
Electrical Characteristics (continued)
(V_AVDD = 3.6V, V_AVSS = 0V, V_DVDD = 2.0V, V_REFP = 2.5V, V_REFN = 0V; f_DATA = 1000sps, External Clock = 8.192MHz; Continuous
conversion mode (SCYCLE = 0); PGA maximum output is 300mV below AVDD and minimum output is 300mV above AVSS,
T_A = T_MIN to T_MAX, unless otherwise noted. Typical values are at T_A = +25°C.) (Note 2)
