250iHP_PGA_01 is a programmable gain amplifier (PGA) with low-pass filter (LPF). The block consists of 2 amplification stages with tunable (5-bit control) gain from 0 to 40dB. Both stages have single-ended input and output and produce max 20dB gain each. Gain can be set by the digital code GC<4:0>. Internal LPF is targeting 15 kHz cut-off frequency. Cut-off frequency adjustment can be held by changing of BW1<3:0> and BW2<3:0> inputs for 1st and 2nd amplifiers respectively. DC offset adjustment can be held by setting of OFFSET1<3:0> and OFFSET2<3:0> inputs. The IP features are low power consumption and compact area.
