DACxx508 and ADS122x04 – Precision ADCs and DACs with small footprint for industrial/personal electronics applications

Texas Instruments has launched four new data converter ICs. The DAC80508 and DAC70508 are Digital to analog converters (DACs) with eight channel precision proving a true resolution of 16-bit/14-bit. The ADS122C04 and ADS122U04 are analog to digital converters (ADCs) with 24-bit precision and features two-wire I2C and UART compatible interface respectively.

All these four data converters are aimed to be used application where space is a strict constraint. They are also claimed to have high performance for a relatively low cost ratio.   

Key features of DAC80508 and DAC70508:

• Channel: 8-channel
• Resolution: 16-bit, 14-bit
• Operating voltage: 2.7V to 5.5V
• Power consumption: 0.6mA per Channel @ 5.5V
• 2.5V Integrated Precision Internal Reference
• 50MHz SPI Serial Interface (Supports daisy chain)
• Package: 2.4mm by  2.4mm (DSBGA) and 3mm by 3mm (WQFN)

Key features of ADS122C04 and ADS122U04:

• Channel: 4-channel
• Resolution: 24-bit
• Operating Voltage: 2.3V to 5.5V
• Power consumption: 315uA (typ)
• Internal 2.048 Reference Voltage
• Oscillator accuracy: 2%
• Gain: 1 to 128
• Communication protocol: I2C(ADS122C04), UART (ADS122U04)
• Package: 3mm by  3mm (WQFN ) and 5mm by 4.4mm (TSSOP)

To help engineers to jump start with their design the data converters also have their own evaluation boards’ available from the TI store and other authorized distributors. The package size and their price with data sheet can be found in the table below.
