2.5 V to 5.5 V, 500 μA, Quad Voltage Output  
8-/10-/12-Bit DACs in 10-Lead Packages  
AD5304/AD5314/AD5324  
Data Sheet  
FEATURES  
GENERAL DESCRIPTION  
The AD5304/AD5314/AD53241 are quad 8-, 10-, and 12-bit  
AD5304: 4 buffered 8-Bit DACs in 10-lead MSOP and  
buffered voltage output DACs in 10-lead MSOP and 10-lead  
LFCSP packages that operate from a single 2.5 V to 5.5 V supply,  
consuming 500 μA at 3 V. Their on-chip output amplifiers allow  
rail-to-rail output swing to be achieved with a slew rate of 0.7 V/μs.  
A 3-wire serial interface is used; it operates at clock rates up to  
30 MHz and is compatible with standard SPI, QSPI, MICROWIRE,  
and DSP interface standards.  
10-lead LFCSP  
A, W Version: 1 LSB INL, B Version: 0.625 LSB INL  
AD5314: 4 buffered 10-Bit DACs in 10-lead MSOP and  
10-lead LFCSP  
A, W Version: 4 LSB INL, B Version: 2.5 LSB INL  
AD5324: 4 buffered 12-Bit DACs in 10-lead MSOP and  
10-lead LFCSP  
A, W Version: 16 LSB INL, B Version: 10 LSB INL  
Low power operation: 500 μA @ 3 V, 600 μA @ 5 V  
2.5 V to 5.5 V power supply  
Guaranteed monotonic by design over all codes  
Power-down to 80 nA @ 3 V, 200 nA @ 5 V  
Double-buffered input logic  
The references for the four DACs are derived from one reference  
pin. The outputs of all DACs can be updated simultaneously using  
LDAC  
the software  
function. The parts incorporate a power-on  
reset circuit, and ensure that the DAC outputs power up to 0 V  
and remains there until a valid write takes place to the device.  
The parts contain a power-down feature that reduces the current  
consumption of the device to 200 nA @ 5 V (80 nA @ 3 V).  
Output range: 0 V to VREF  
Power-on reset to 0 V  
The low power consumption of these parts in normal operation  
makes them ideally suited to portable battery-operated equipment.  
The power consumption is 3 mW at 5 V, 1.5 mW at 3 V, reducing  
to 1 μW in power-down mode.  
LDAC  
Simultaneous update of outputs (  
function)  
Low power-, SPI®-, QSPI™-, MICROWIRE™-, and DSP-  
compatible 3-wire serial interface  
On-chip, rail-to-rail output buffer amplifiers  
Temperature range −40°C to +105°C  
Qualified for automotive applications  
APPLICATIONS  
Portable battery-powered instruments  
Digital gain and offset adjustment  
Programmable voltage and current sources  
Programmable attenuators
