The document describes the features and characteristics of the PGA202/203 products, including programmable gains, low bias current, fast settling, and low non-linearity.
The PGA202 provides gains of 1, 10, 100, and 1000, while the PGA203 offers gains of 1, 2, 4, and 8. Both devices feature TTL or CMOS-compatible inputs for easy microprocessor interfacing and utilize a new transconductance circuitry to maintain nearly constant bandwidth with gain changes.
The document outlines electrical specifications including low bias current (50pA max), fast settling times (2µs to 10µs depending on gain), and high common-mode rejection ratio. It also provides pin configurations, typical performance curves, offset adjustment circuit diagrams, and ordering information for various package types.
| Input Bias Current (Initial) | 50pA max at +25°C |
|---|---|
| Settling Time (G=1) | 2µs to 0.01% |
| Common-Mode Rejection Ratio | 80dB min |
The PGA203 provides gains of 1, 2, 4, and 8.
The maximum initial input bias current is 50 pA at +25°C.
