Part Number: ADS131E08 Hello sir, We are working on New project called 4-Channel ADC card Please suggest me relevant part for following section. The Requirements are 1). Low Noise Amplifier spec. Voltage Noise : 10 nV/√Hz Current Noise : 1 fA /√Hz Very low input bias current Fixed Gain : 40 dB 2). Charge Amplifier spec. Voltage Noise : 10 nV/√Hz Current Noise : 1 fA /√Hz Very low input bias current Fixed Gain : 40 dB 3). Programmable Gain Amplifier spec. Variable gain of 0 to 60 dB with minimum gain step variation 1dB. Minimum Supply Voltage : ±2.5V 4). Anti-aliasing Filter spec 4 or 8th order Elliptical LPF Filter or Butter-worth LPF Filter with unity gain Cutoff frequency: 4 kHz 5). 4-Channel 24-bit ADC spec 24-Bit resolution Support Simultaneously-Sampling support minimum Sampling rate : 12.8 kHz Suggest me the op-amp, PGA & 24-Bit ADC relevant part for above specification. Hereby enclosed our project Block diagram for your reference. (Please visit the site to view this file) Note:- Supply Voltage for all op-amp signal conditioning section work with ±2.5V or ±5V Regards Lakshmanan V
