Design an Analog Universal Input Signal for ADC

The freelancer has to design an Analog Universal Input for an A/D converter, of minimum 16-bits resolution. This analog circuit must have the following features:

- Programmable input: Pt100 RTD and thermocouples type J, K, T, E, N, R, S, B.

- Two-wire loop powered 4-20 mA output

- Voltage input of 0-10, 0-5VDC

- Linearized output and cold junction compensation for thermocouples.

- 2 or 3-wire Pt100 with linearization.

- Isolation: 1500 VDC.

- Programmable working range by Bluetooth with App on Android/iOS

- Manual zero (offset) adjustment

- Accuracy: ±0.2% full scale for Pt100 and 0.3% max. of FS for thermocouples

- Temperature effect: 0.003% SPAN/°C

- Working temperature: -40 to +85 °C

- Programmable burnout upscale or downscale sensor failure protection

Any improvement in the features are welcome!
