ADS1204
- 16-bit resolution
- 14-bit linearity
- Resolution, speed trade-off:
10-bit effective resolution with 10-µs signal delay (12-bit with 19 µs) - ±2.5-V input range at 2.5 V
- Internal reference voltage: 2%
- Gain error: 0.5%
- Four independent delta-sigma modulators
- Four input reference buffers
- Onboard 20-MHz oscillator
- Selectable internal or external clock
- Operating temperature range:
–40°C to +105°C - Package: VQFN-32 (5 mm × 5 mm)
The ADS1204 is a four-channel, high-performance device, with four delta-sigma (ΔΣ) modulators with 100-dB dynamic range, operating from a single 5-V supply. The differential inputs are ideal for direct connection to transducers in an industrial environment. With the appropriate digital filter and modulator rate, the device can be used to achieve 16-bit analog-to-digital (A/D) conversion with no missing code. Effective resolution of 12 bits can be obtained with a digital filter data rate of 160 kHz at a modulator rate of 10 MHz. The ADS1204 is designed for use in medium- to high-resolution measurement applications including current measurements, smart transmitters, industrial process control, weight scales, chromatography, and portable instrumentation. It is available in a VQFN-32 (5×5) package.
