MAX1277_09 Datasheet, PDF (5/18 Pages) Maxim Integrated Products – 1.5Msps, Single-Supply, Low-Power, True-Differential, 12-Bit ADCs with Internal Reference

1.5Msps, Single-Supply, Low-Power, True-
Differential, 12-Bit ADCs with Internal Reference
Typical Operating Characteristics
(V_DD = +3V, V_L = V_DD, f_SCLK = 24MHz, f_SAMPLE = 1.5Msps, T_A = -40°C to +85°C, unless otherwise noted. Typical values are mea-
sured at T_A = +25°C.)
