Product Overview
The DAC121S101 is a Texas Instruments Signal_Chain 12-bit voltage-output DAC. Its output range is specified from 0 to VA, with recommended supply operation from 2.7 to 5.5 V and SCLK operation up to 30 MHz. Resolution and monotonicity are both specified at 12 bits over the full operating temperature range.
Package options include a 6-pin SOT (DDC) measuring 2.90 mm x 1.60 mm and an 8-pin VSSOP (DGK) measuring 3.00 mm x 3.00 mm. Thermal resistance is specified as 250 °C/W for the 6-pin DDC SOT and 240 °C/W for the 8-pin DGK VSSOP. Operating temperature coverage is -40 to +105 °C for DAC121S101 and -40 to +125 °C for DAC121S101-Q1.
Analog performance includes ±2.6 LSB typical integral non-linearity over decimal codes 48 to 4047, 1.3 Ω typical DC output impedance, and 8 µs typical settling time. The device supports output load capacitance up to 1500 pF and includes power-down operating data down to 0.07 µA typical at 5.5 V and 0.04 µA typical at 3.6 V when fSCLK=0.
