JFET-Input Op Amps offer fast slew rates.
Press Release Summary:
Offered in VSON-8 or SOT23-5 packages, OPA653/OPA659 combine wideband voltage feedback amplifier with JFET-input stage and meet requirements for frequency domain and FFT analysis due to their respective signal bandwidths of 475 and 575 MHz and THD ratings of -60 and -66 dBc @ 100 MHz. Optimal pulse response is due to respective 2,675 and 2,550 V/µs slew rates of fixed gain (+2 V/V) OPA653 and unity gain stable OPA659. Both offer settling time of 8 ns and overdrive recovery of 8 ns.
Original Press Release:
TI Introduces Industry's Fastest JFET-Input Amplifiers
DALLAS -- Texas Instruments Incorporated (TI) (NYSE: TXN) today introduced the OPA653 and OPA659 JFET-input operational amplifiers, which provide a slew rate of up to 2675 V/us, three times faster than that of the nearest competitor, resulting in improved pulse response. These amplifiers combine a wideband voltage feedback amplifier with a high-impedance JFET-input stage and meet the requirements for frequency domain and FFT analysis due to their large signal bandwidth and low total harmonic distortion. See more product details at www.ti.com/opa659-pr.
Key features and benefits of the OPA653 and OPA659
-- Best-in-class slew rate and low distortion contribute to enhanced signal integrity for time-domain and pulse-oriented applications.
- The OPA653 is a fixed gain (+2 V/V) JFET-input amplifier with a slew rate of 2675 V/microns and 475 MHz of large signal bandwidth (2 Vp-p).
- The OPA659 is a unity gain stable JFET-input amplifier with a slew rate of 2550 V/µs and 575 MHz of large signal bandwidth (2 Vp-p).
- Third order harmonic distortion (HD3) of -60 dBc (OPA659) and -66 dBc (OPA653) at 100 MHz ensures superior high-bandwidth linearity.
-- Fast settling time (8 ns) and overdrive recovery (8 ns) enable excellent pulse response.
-- The OPA653's ultra-low overshoot and ringing are desirable in low-noise, wideband, high input impedance applications such as data acquisition cards, high-impedance probes and oscilloscope front ends.
-- The OPA659's 350-MHz high gain bandwidth optimizes machine vision applications, such as broadband photodiode transimpedance amplifiers used in wafer inspection equipment.
-- Power supply voltage range of +/-3.5 V to +/- 6.4 V maximizes design flexibility.
-- These devices drive TI's 12- and 14-bit, 400-MSPS and 500-MSPS analog-to-digital converters including the ADS5474, ADS5463 and ADS54RF63.
Availability and pricing
The OPA653 and OPA659 devices are both available in VSON-8 or SOT23-5 packages and priced at $2.95 in 1,000-piece quantities.
