TLV5619CPW

2.7 V至5.5 V 12位并行数字 - 模拟与POWER DOWN转换器 2.7 V TO 5.5 V 12-BIT PARALLEL DIGITAL-TO-ANALOG CONVERTER WITH POWER DOWN

DESCRIPON

The TLV5619 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 dissi-pates 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.
