I don't think the VREF circuit you have shown there will give very good performance I would recommend using the REF5040 instead, tying the GND pin on the REF5040 and REFN on the ADS1158 to AVSS (-2.5 V) and supplying VIN on the REF5040 with 2.5 V

ADS1158 Data apparently incorrect in some cases while measuring a

The ADS1158 is a 16-channel (multiplexed), low-noise, 16-bit, delta-sigma (ΔΣ) analog-to-digital converter (ADC) that provides single-cycle settled data at channel scan rates from 1.8k to 23.7k samples per second (SPS) per channel VREF = 2,5V, VREFN, AINCOM, AVSS and thermal pad connected to GND The related documents listed in Table 1 are available through the Texas Instruments web site at.

ADS1158 Open Sensor Detection Data converters forum Data converters. The ADS1158 differential input range extends from +1.066*VREF to -1.066*VREF, so if your input signals are single-ended you are only using the positive half of the ADC codes. A flexible input multiplexer accepts combinations of eight differential or 16 single-ended inputs with a full-scale differential range of 5V or true bipolar range.

ADS1158 Lower than expected samples per second Data converters forum. When AINCOM = +VREF/2, the output code is 0x8000 to 0x7FFF These statements are correct All inputs AIN0 to AIN16 are protected with an 4.7k series resistor
