Part Details:

2.5 V to 5.5 V Octal Voltage Output 8-/10-/12-Bit DACs in 16-Lead TSSOP AD5308/AD5318/AD5328 FEATURES APPLICATIONS AD5308: 8 buffered 8-bit DACs in 16-lead TSSOP Portable battery-powered instruments A version: ±1 LSB INL, B version: ±0.75 LSB INL Digital gain and offset adjustment AD5318: 8 buffered 10-bit DACs in 16-lead TSSOP Programmable voltage and current sources A version: ±4 LSB INL, B version: ±3 LSB INL Optical networking AD5328: 8 buffered 12-bit DACs in 16-lead TSSOP Automatic test equipment A version: ±16 LSB INL, B version: ±12 LSB INL Mobile communications Low power operation: 0.7 mA @ 3 V Programmable attenuators Guaranteed monotonic by design over all codes Industrial process control Power-down to 120 nA @ 3 V, 400 nA @ 5 V Double-buffered input logic Buffered/unbuffered/VDD reference input options Output range: 0 V to VREF or 0 V to 2 VREF Power-on reset to 0 V Programmability Individual channel power-down Simultaneous update of outputs (LDAC) Low power, SPI-®, QSPI-TM, MICROWIRE-TM, and DSP- compatible 3-wire serial interface On-chip rail-to-rail output buffer amplifiers Temperature range: -40°C to +105°C GENERAL DESCRIPTION The AD5308/AD5318/AD5328 are octal 8-, 10-, and 12-bit incorporate a power-on reset circuit, which ensures that the buffered voltage output DACs in a 16-lead TSSOP. They operate DAC outputs power up to 0 V and remain there until a valid from a single 2.5 V to 5.5 V supply, consuming 0.7 mA typical write to the device takes place. The outputs of all DACs may be at 3 V. Their on-chip output amplifiers allow the outputs to updated simultaneously using the asynchronous LDAC input. swing rail-to-rail with a slew rate of 0.7 V/s. The AD5308/ The parts contain a power-down feature that reduces the current AD5318/AD5328 use a versatile 3-wire serial interface that consumption of the devices to 400 nA at 5 V (120 nA at 3 V). operates at clock rates up to 30 MHz and is compatible with The eight channels of the DAC may be powered down individually. standard SPI, QSPI, MICROWIRE, and DSP interface All three parts are offered in the same pinout, which allows standards. users to select the resolution appropriate for their application The references for the eight DACs are derived from two without redesigning their circuit board. reference pins (one per DAC quad). These reference inputs can be configured as buffered, unbuffered, or VDD inputs. The parts
