6350f

Note 1: Stresses beyond those listed under Absolute Maximum Ratings

may cause permanent damage to the device. Exposure to any Absolute

Maximum Rating condition for extended periods may affect device

reliability and lifetime.

Note 2: Inputs are protected by back-to-back diodes and diodes to each

supply. If the inputs are taken beyond the supplies or the differential input

voltage exceeds 0.7V, the input current must be limited to less than 20mA.

Note 3: A heat sink may be required to keep the junction temperature

below the absolute maximum rating when the output is shorted indeﬁnitely.

Note 4: The LT6350C/LT6350I are guaranteed functional over the

temperature range of –40°C to 85°C. The LT6350H is guaranteed

functional over the temperature range of –40°C to 125°C.

Note 5: The LT6350C is guaranteed to meet speciﬁed performance from

0°C to 70°C. The LT6350C is designed, characterized and expected to

meet speciﬁed performance from –40°C to 85°C, but is not tested or

QA sampled at these temperatures. The LT6350I is guaranteed to meet

speciﬁed performance from –40°C to 85°C. The LT6350H is guaranteed to

meet speciﬁed performance from –40°C to 125°C.

Note 6: VOS2 is measured as the total output common mode voltage offset

(error between output common mode and voltage at V2). VOS2 includes

the combined effects of op amp 2’s voltage offset, IB, IOS and mismatch

between on-chip resistors and the 499Ω external resistor, R1 (See Figure 1).

Note 7: Supply voltage range is guaranteed by the power supply rejection

ratio test.

Note 8: Output balance is calculated from gain error and gain as:

Note 9: DC linearity is measured by measuring the differential output for

each input in the set V+IN1 = 0.5V, 2.5V, 4.5V, and calculating the maximum

deviation from the least squares best ﬁt straight line generated from the

three data points.

Note 10: Output voltage swings are measured between the output and

power supply rails.

Note 11: Full- power bandwidth is calculated from the slew rate.

FPBW = SR/2VP.

ELECTRICAL CHARACTERISTICS The l denotes speciﬁcations that apply over the full speciﬁed temperature range,

otherwise speciﬁcations are at TA = 25°C. Unless noted otherwise, V+ = 5V, V– = 0V, V+IN1 = V2 = Mid-Supply, VSHDN = V+, RL = OPEN, RF =

SHORT, RG = OPEN. VS is deﬁned as (V+ – V–). VOUTCM is deﬁned as (VOUT1 + VOUT2)/2. VOUTDIFF is deﬁned as (VOUT1 – VOUT2). See Figure 1.
