It is a small, robust unit and uses a GRAS CCP power supply, e.g., GRAS 12AL. It has a very low inherent noise level, a large dynamic range, and a frequency response from below 2 Hz to above 200 kHz.\u003c\/p\u003e\n\u003cp\u003eIts small ceramic thick-film substrate has a very high input impedance and is shielded by a guard ring to minimize the influence of stray capacitance and microphonic interference.The GRAS 26CB is delivered with a built-in TEDS chip and can be programmed as a single unit with a microphone fitted.\u003c\/p\u003e\n\u003cp\u003eThe diameter is 6.35 mm (1\/4\"), length 44 mm and weight 19 g (0.67 oz)\u003c\/p\u003e\n\u003c\/div\u003e\n\u003ch2 class=\"h4\"\u003eKey Specifications\u003c\/h2\u003e\n\u003cdiv style=\"overflow-x:auto;\"\u003e\u003ctable style=\"width:100%;border-collapse:collapse;\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:6px;\"\u003e\u003cstrong\u003eFrequency range (±0.2 dB) with 18 pF microphone dummy\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:6px;\"\u003e2.5 Hz to 200 kHz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:6px;\"\u003e\u003cstrong\u003eSlew rate\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:6px;\"\u003e20 V\/µs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:6px;\"\u003e\u003cstrong\u003eInput impedance\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:6px;\"\u003e20 \/\/ 0.4 GΩ \/\/ pF\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:6px;\"\u003e\u003cstrong\u003eOutput impedance\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"border:1px solid #ddd;padding:6px;\"\u003e\u0026lt;
