INSTRUMENTATION AMPLIFIER  
FEATURES  
DIGITALLY PROGRAMMABLE GAIN:  
DESCRIPTION  
The PGA204 and PGA205 are low cost, general pur-  
pose programmable-gain instrumentation amplifiers  
offering excellent accuracy. Gains are digitally se-  
lected: PGA204—1, 10, 100, 1000, and PGA205—1,  
2, 4, 8V/V. The precision and versatility, and low cost  
of the PGA204 and PGA205 make them ideal for a  
wide range of applications.  
PGA204: G=1, 10, 100, 1000V/V  
PGA205: G=1, 2, 4, 8V/V  
LOW OFFSET VOLTAGE: 50µV max  
LOW OFFSET VOLTAGE DRIFT: 0.25µV/°C  
LOW INPUT BIAS CURRENT: 2nA max  
LOW QUIESCENT CURRENT: 5.2mA typ  
NO LOGIC SUPPLY REQUIRED  
Gain is selected by two TTL or CMOS-compatible  
address lines, A0 and A1. Internal input protection can  
withstand up to ±40V on the analog inputs without  
damage.  
16-PIN PLASTIC DIP, SOL-16 PACKAGES  
The PGA204 and PGA205 are laser trimmed for very  
low offset voltage (50µV), drift (0.25µV/°C) and high  
common-mode rejection (115dB at G=1000). They op-  
erate with power supplies as low as ±4.5V, allowing use  
in battery operated systems. Quiescent current is 5mA.  
APPLICATIONS  
DATA ACQUISITION SYSTEM  
GENERAL PURPOSE ANALOG BOARDS  
MEDICAL INSTRUMENTATION  
The PGA204 and PGA205 are available in 16-pin  
plastic DIP, and SOL-16 surface-mount packages, speci-  
fied for the –40°C to +85°C temperature range.
