ADS7067 Small, 8-Channel, 16-Bit, 800-kSPS SAR ADC With GPIOs

1 Features

3 Description

•

Small solution size:

The ADS7067 is a small, 16-bit, 8-channel, high-

precision successive-approximation register (SAR)

analog-to-digital converter (ADC). The ADS7067 has

an integrated capless reference and a reference

buffer that helps reduce the overall solution size by

requiring fewer external components. The wafer-level-

chip-scale package and fewer external components

make this device suitable for space-constrained

applications. The device family includes the ADS7067

(800 kSPS) and the ADS7066 (250 kSPS) speed

variants.

– 1.62-mm × 1.62-mm WCSP

– Space-saving, capless, 2.5-V internal reference

8 channels configurable as any combination of:

– Up to 8 analog inputs, digital inputs, or digital

outputs

Programmable averaging filters:

– Programmable sample size for averaging

– Averaging with internal conversions

– 20-bit resolution for average output

Low-leakage multiplexer with channel sequencer:

– Manual mode

•

The ADS7067 features built-in offset calibration for

improved accuracy over wide operating conditions

of the system. The programmable averaging filters

enable higher resolution measurement. The eight

channels of the ADS7067 can be individually

configured as analog inputs, digital inputs, or digital

outputs that enable smaller system size and simplify

circuit design for mixed signal feedback and digital

control.

– On-the-fly mode

– Auto-sequence mode

Excellent AC and DC performance:

– SNR: 90 dB, THD: –100 dB

– Improved SNR with programmable averaging

filters

– INL: ±1 LSB, 16-bit no missing codes

– Internal calibration improves offset and drift

– High sample rate with no latency output:

800 kSPS

The enhanced-SPI enables the ADS7067 in achieving

high throughput at lower clock speeds, thereby

simplifying the board layout and lowering system cost.

The ADS7067 features a cyclic redundancy check

(CRC) for data read and write operations and the

power-up configuration.

•

Wide operating range:

– ADC input range: 0 V to V_REFand 2 × V_REF

– Analog supply: 3 V to 5.5 V

– Digital supply: 1.65 V to 5.5 V

– Temperature range: –40°C to +125°C

Enhanced-SPI digital interface:

– High-speed, 60-MHz SPI interface
