PGA102
High Speed PROGRAMMABLE GAIN AMPLIFIER
FEATURES
q DIGITALLY PROGRAMMABLE GAIN: G = 1, 10, 100 q LOW GAIN ERROR: 0.025% max q FAST SETTLING: 2.8µs to 0.01% q 16-PIN PLASTIC AND CERAMIC DIP
DESCRIPTION
The PGA102 is a high speed, digitally programmablegain amplifier. CMOS/TTL-compatible inputs select gains of 1, 10 or 100V/V. Each gain has an independent input terminal, providing an input multiplexer function. On-chip metal film gain-set resistors are laser-trimmed to provide excellent gain accuracy. High speed input circuitry allows multiplexing of high speed signals. The PGA102 is available in 16-pin plastic and ceramic DIP packages. Commercial, industrial and military temperature range models are available.

* Specification same as AG grade. NOTES: (1) Gain inaccuracy is the percent error between the actual and ideal gain selected. It may be externally adjusted to zero for gains of 10 and 100. (2) Offset voltage can be adjusted for any one channel. Adjustment affects temperature drift by approximately ±0.3µV/°C for each 100µV of offset adjusted. (3) Voltage on the logic threshold control pin, VLTC, adjusts the threshold for "Low" and "High" logic levels. (4) Total time to settle equals switching time plus settling time of the newly selected gain.
