description
The TL V5619 is a 12-bit voltage output DAC with a microprocessor and TMS320 compatible parallel interface. The 12 data bits are double buffered so that the output can be updated asynchronously using the LDAC
pin. During normal operation, the device dissipates 8 mW at a 5-V supply and 4.3 mW at a 3-V supply. The power consumption can be lowered to 50 nW by setting the DAC to power-down mode.
The output voltage is buffered by a ×2 gain rail-to-rail amplifier, which features a Class A output stage to improve stability and reduce settling time.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

NOTES: 3. The relative accuracy or integral nonlinearity (INL), sometimes referred to as linearity error, is the maximum deviation of the output
from the line between zero and full scale excluding the effects of zero code and full-scale errors.
4. The differential nonlinearity (DNL), sometimes referred to as differential error, is the difference between the measured and ideal 1 LSB amplitude change of any two adjacent codes. Monotonic means the output voltage changes in the same direction (or remains constant) as a change in the digital input code.
5. Zero-scale error is the deviation from zero voltage output when the digital input code is zero.
6. Zero-scale-error temperature coefficient is given by: EZSTC = [EZS(T
max
) – EZS(T
min
)]/V
ref
× 106/(T
max
– T
min
).
7. Gain error is the deviation from the ideal output (2 × V
ref
– 1 LSB) with an output load of 10 kexcluding the effects of the zero-error.
8. Gain temperature coefficient is given by: EGTC = [EG(T
max
) – EG (T
min
)]/V
ref
× 106/(T
max
– T
min
).
9. Zero-scale-error rejection ratio (EZS-RR) is measured by varying the VDD from 4.5 V to 5.5 V dc and measuring the proportion of this signal imposed on the zero-code output voltage.
10. Gain-error rejection ratio (EG-RR) is measured by varying the VDD from 4.5 V to 5.5 V dc and measuring the proportion of this signal imposed on the full-scale output voltage after subtracting the zero scale change.
