ELECTRICAL CHARACTERISTICS (for V± = ±2.5V ±5%)
(V+ = +2.37V, V- = -2.37V, CLKA = CLKB = ±2.5V 250kHz for the MAX260 and 1MHz for the MAX261/MAX262, fCLK/f0 = 199.49 for
MAX260/MAX261 and 139.80 for MAX262, Filter Mode 1, TA = +25°C, unless otherwise noted.)

Note 1: fCLK/f0 accuracy is tested at 199.49 on the MAX260/MAX261, and at 139.8 on the MAX262.
Note 2: Q accuracy tested at Q = 8, 32, and 64. Q of 32 and 64 tested at 1/2 stated clock frequency.
Note 3: The offset voltage is specified for the entire filter. Offset is virtually independent of Q and fCLK/f0 ratio setting. The test clock
frequency for mode 3 is 175kHz for the MAX260 and 750kHz for the MAX261/MAX262.
Note 4: Output noise is measured with an RC output smoothing filter at 4 f0 to remove clock feedthrough.
Note 5: TTL logic levels are: HIGH = 2.4V, LOW = 0.8V. CMOS logic levels are: HIGH = 5V, LOW = 0V. Power supply current is typi-
cally 4mA higher with TTL logic and clock input levels.
Note 6: On the MAX260 only, the HP output signal swing is typically 0.75V less than the LP or BP outputs.
Note 7: At ±2.5V supplies, the f0 range and maximum clock frequency are typically 75% of values listed in Table 1.
Note 8: fCLK/f0 and Q accuracy are a function of the accuracy of internal capacitor ratios. No increase in error is expected at ±2.5V
as compared to ±5V; however, these parameters are only tested to the extent indicated by the MIN or MAX limits.
