DESCRIPTION/ORDERING INFORMATION
The THS4513 is a wideband, fully differential op amp
designed for 3.3 V to 5 V data-acquisition systems. It
has very low noise at 2.2 nV/√Hz, and extremely low
harmonic distortion of –76 dBc HD₂ and –88 dBc HD₃
at 70 MHz with 2 Vpp output, G = 14 dB, and 100 Ω
load. Slew rate is very high at 5100 V/μs and with
settling time of 5.5 ns to 1% (2 V step), it is ideal for
pulsed applications. It is suitable for minimum gain of
6 dB.
To allow for dc coupling to ADCs, its unique output
common-mode control circuit maintains the output
common-mode voltage within 5 mV offset (typ) from
the set voltage, when set within 0.5 V of mid-supply,
with less than 4 mV differential offset voltage. The
common-mode set point is set to mid-supply by
internal circuitry, which may be over-driven from an
external source.
The input and output are optimized for best
performance with their common-mode voltages set to
mid-supply. Along with high performance at low
power supply voltage, this makes for extremely high
performance single supply 5 V data acquisition
systems.
The THS4513 is offered in a 16-pin ceramic flatpack
package (W), and is characterized for operation over
the full military temperature range from –55°C to
125°C.
