7 / 20 page LTC2630 7 2630f ELECTRICAL CHARACTERISTICS The ● denotes the specifications which apply over the full operating temperature range, otherwise specifications are at TA = 25°C. VCC = 4.5V to 5.5V, VOUT unloaded unless otherwise specified. LTC2630-HM12/-HM10/-HM8/-HZ12/-HZ10/-HZ8, LTC2630A-HM12/-HZ12 (VFS = 4.096V) SYMBOL PARAMETER CONDITIONS MIN TYP MAX UNITS AC Performance tS Settling Time VCC = 5V (Note 7) ±0.39% (±1LSB at 8 Bits) ±0.098% (±1LSB at 10 Bits) ±0.024% (±1LSB at 12 Bits) 3.7 4.4 4.8 μs μs μs Voltage Output Slew Rate 1.0 V/ μs Capacitive Load Driving 500 pF Glitch Impulse At Midscale Transition 2.4 nV•s en Output Voltage Noise Density At f = 1kHz, Supply as Reference At f = 10kHz, Supply as Reference At f = 1kHz, Internal Reference At f = 10kHz, Internal Reference 140 130 210 200 nV/√Hz nV/√Hz nV/√Hz nV/√Hz Output Voltage Noise 0.1Hz to 10Hz, Supply as Reference 0.1Hz to 10Hz, Internal Reference 0.1Hz to 200kHz, Supply as Reference 0.1Hz to 200kHz, Internal Reference 20 20 650 750 μVP-P μVP-P μVP-P μVP-P 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: Linearity and monotonicity are defined from code kL to code 2 N–1, where N is the resolution and kL is given by kL = 0.016 • (2 N/ VFS), rounded to the nearest whole code. For VFS = 2.5V and N = 12, kL = 26 and linearity is defined from code 26 to code 4,095. For VFS = 4.096V and N = 12, kL = 16 and linearity is defined from code 16 to code 4,095. Note 3: Inferred from measurement at code 16 (LTC2630-12), code 4 (LTC2630-10) or code 1 (LTC2630-8). Note 4: This IC includes current limiting that is intended to protect the device during momentary overload conditions. Junction temperature can exceed the rated maximum during current limiting. Continuous operation above the specified maximum operating junction temperature may impair device reliability. Note 5: Digital inputs at 0V or VCC. Note 6: Guaranteed by design and not production tested. Note 7: Internal Reference mode. DAC is stepped 1/4 scale to 3/4 scale and 3/4 scale to 1/4 scale. Load is 2k Ω in parallel with 100pF to GND. Note 8: Temperature coefficient is calculated by dividing the maximum change in output voltage by the specified temperature range. TIMING CHARACTERISTICS The ● denotes the specifications which apply over the full operating temperature range, otherwise specifications are at TA = 25°C. VCC = 4.5V to 5.5V. (See Figure 1) (Note 6).
