4 / 30 page LOG114 SBOS301A − MAY 2004 − REVISED MARCH 2007 www.ti.com 4 ELECTRICAL CHARACTERISTICS: VS = +5V (continued) Boldface limits apply over the specified temperature range, TA = −5°C to +75°C. All specifications at TA = +25°C, RVLOGOUT = 10kΩ, VCM = GND, unless otherwise noted.

Scale factor, K, equals 0.375V output per decade of input current. (2) Scale factor of core log function is trimmed to 0.375V output per decade change of input current. (3) Specified by design. (4) Worst-case total error for any ratio of I1/I2, as the largest of the two errors, when I, and I2 are considered separately. (5) Total error includes offset voltage, bias current, gain, and log conformity. (6) Small signal bandwidth (3dB) and transient response are a function of the level of input current. Smaller input current amplitude results in lower bandwidth. |
