4 / 12 page LTC1659 4 1659fa ELECTRICAL CHARACTERISTICS The ● denotes the specifications which apply over the full operating temperature range, otherwise specifications are at TA = 25°C. VCC = 2.7V to 5.5V, VOUT unloaded, REF ≤ VCC, TA = TMIN to TMAX unless otherwise noted.

Exposure to any Absolute Maximum Rating condition for extended periods may affect device reliability and lifetime. Note 2: Nonlinearity is defined from code 20 to code 4095 (full scale). See Applications Information. Note 3: Load is 5k Ω in parallel with 100pF. Note 4: DAC switched between all 1s and the code corresponding to VOS for the part. Note 5: Digital inputs at 0V or VCC. Note 6: VOUT can only swing from (GND + |VOS|) to (VCC – |VOS|) when output is unloaded. Note 7: Guaranteed by design, not subject to test. |
