Conditions
Pin INHI, Pin INLO
VDBS = 0 V, differential drive
VDBS = 1.5 V
Pin-to-pin
Either pin to COMM
f = 1 MHz, VDBS = 1.5 V; inputs ac-shorted
Pin OFST connected to Pin COMM
f = 1 MHz, 0.1 V rms
f = 50 MHz
Pin OPHI, Pin OPLO
0 V < VDBS < 1.5 V
VDBS = 0 V
VMAG ≥ 2 V (peaks are supply limited)
Pin CNTR O/C
f = 1 MHz, VDBS = 0 V
Pin-to-pin
VOUT = 1 V p-p, f = 10 MHz, RL = 1 kΩ
VOUT = 1 V p-p, f = 10 MHz, RL = 1 kΩ
Pin OFST
CHPF on Pin OFST (0 V < VDBS < 1.5 V)
CHPF = 3.3 nF, from OFST to CNTR (scales as 1/CHPF)
Pin CNTR
From Pin CNTR to VS/2
VDBS, CMGN, and MODE pins
CMGN connected to COMM
CMGN O/C (VCMGN rises to 0.2 V)
Mode high or low
0.3 V ≤ VDBS ≤ 1.2 V
VDBS = 0 V
Flows out of Pin VDBS
VDBS stepped from 0.05 V to 1.45 V or 1.45 V to 0.05 V
Pin MODE
Gain increases with VDBS, MODE = O/C
Gain decreases with VDBS
Pin VMAG, Pin CMGN
See the Circuit Description section
Gain is nominal when VMAG = 0.5 V
VMAG O/C
For VMAG ≥ 0.1 V
