ADS7800JU

The ADS7800JU is a complete 12-bit successive approximation analog-to-digital converter (ADC) from Texas Instruments, built with state-of-the-art CMOS structures. It integrates a 12-bit SAR ADC with internal sample/hold, voltage reference, clock, and a digital interface for microprocessor control, plus three-state output drivers.

Key specifications include a 333 kSPS maximum sampling rate, single-ended input with a ±10 V range, and internal reference mode. The device operates from analog and digital supplies of 4.75 V to 5.25 V, with typical power consumption of 135 mW and maximum power dissipation of 215 mW. It delivers 73 dB SNR, 80 dB SFDR, and -80 dB THD, with integral nonlinearity of 0.5 LSB max and differential nonlinearity of 0.75 LSB max.

The ADC is rated for industrial temperature range (-40°C to 85°C) and is offered in a surface-mount 24-SOIC package (0.295" width, 7.50 mm). It is suitable for applications requiring precise analog-to-digital conversion with moderate speed and low power.
