ADS1201U

ADS1201U is a high-precision analog-to-digital converter (ADC) in TI’s ADS1200 family. It uses a delta-sigma architecture to convert small analog signals into high-resolution digital data, suitable for precision measurement.
Key features (typical, variants may differ):
- SPI-/Serial-compatible interface for digital output
- Differential input with programmable gain or input range
- Programmable data rate and digital filtering
- Low noise, good DC accuracy, and relatively low power for precision applications
Common applications:
- Precision instrumentation
- Weigh scales and load cells
- Industrial/process control
- Sensor front-ends and data acquisition
How it works:
- Analog input is converted by a delta-sigma modulator
- Digital filtering produces a high-resolution output word
- Data is read via the serial interface
Notes:
- Exact specs (resolution, data rate, input range, supply, temperature grade) vary by variant and package.
- For precise features and pinout, consult the official ADS1201U datasheet and application notes.

Here are the typical features of the ADS1201U (TI) family:
- 24-bit delta-sigma ADC with high-resolution conversion
- Differential input with programmable input range
- SPI-compatible serial interface (CLK, CS, DIN, DOUT)
- Programmable gain amplifier (PGA) with multiple gain settings
- Internal reference and/or external reference support
- Programmable data rate and selectable digital filter
- On-chip clock option and compatibility with external clock
- Data-ready/interrupt signaling
- Power-down/standby mode for low power
- Low-noise, low-drift performance with good CMRR
- Wide operating temperature range (industrial-grade)
- Flexible supply options and small package variants
Note: exact specs (data rate, input ranges, and package options) may vary by revision; please consult the current datasheet for precise details.

- Pin count: 8 pins (8-pin package, e.g., SOIC/MSOP)
- Function (typical SPI delta‑sigma ADC interface):
- VDD: Power supply
- GND: Ground
- CS: Chip select (SPI)
- SCLK: Serial clock
- DIN: Serial data input
- DOUT: Serial data output
- CNV (or START): Convert/start conversion input
- DRDY (RDY): Data-ready output (conversion complete)
Note: pin names can vary slightly by package.
